# MouseSubregion

from pandac.PandaModules import MouseSubregion

Class : MouseSubregion
Description : The MouseSubregion object scales the mouse inputs from within a rectangular region of the screen, as if they were the full-screen inputs.
If you choose your MouseSubregion coordinates to exactly match a DisplayRegion within your window, you end up with a virtual mouse within your DisplayRegion.

getTop float MouseSubregion::get_top(void) const; Description: Retrieves the y coordinate of the top edge of the rectangle within the window. This number will be in the range [0..1].

setDimensions void MouseSubregion::set_dimensions(float l, float r, float b, float t); Description: Changes the region of the window in which the mouse is considered to be active. The parameters are identical to those for a DisplayRegion: they range from 0 to 1, where 0,0 is the lower left corner and 1,1 is the upper right; (0, 1, 0, 1) represents the whole window.

clearAllButtons void MouseInterfaceNode::clear_all_buttons(void); Description: Removes all requirements on buttons set by an earlier call to require_button().

clearButton void MouseInterfaceNode::clear_button(ButtonHandle const &button); Description: Removes any requirement on the indicated button set by an earlier call to require_button().

getClassType static TypeHandle MouseInterfaceNode::get_class_type(void); Undocumented function.

requireButton void MouseInterfaceNode::require_button(ButtonHandle const &button, bool is_down); Description: Indicates that the indicated button must be in the required state (either up or down) in order for this particular MouseInterfaceNode to do anything. For instance, this may be called to make a Trackball object respect mouse input only when the control key is held down.

getClassType static TypeHandle DataNode::get_class_type(void); Undocumented function.

writeConnections void DataNode::write_connections(ostream &out) const; Description: Writes to the indicated ostream a list of all the connections currently showing between this DataNode and its parent(s).

writeInputs void DataNode::write_inputs(ostream &out) const; Description: Writes to the indicated ostream a list of all the inputs this DataNode might expect to receive.

writeOutputs void DataNode::write_outputs(ostream &out) const; Description: Writes to the indicated ostream a list of all the outputs this DataNode might generate.

addChild void PandaNode::add_child(PandaNode *child_node, int sort = (0)); Description: Adds a new child to the node. The child is added in the relative position indicated by sort; if all children have the same sort index, the child is added at the end. If the same child is added to a node more than once, the previous instance is first removed.

addStashed void PandaNode::add_stashed(PandaNode *child_node, int sort = (0)); Description: Adds a new child to the node, directly as a stashed child. The child is not added in the normal sense, but will be revealed if unstash_child() is called on it later. If the same child is added to a node more than once, the previous instance is first removed. This can only be called from the top pipeline stage (i.e. from App).

adjustDrawMask void PandaNode::adjust_draw_mask(BitMask< unsigned int, 32 > show_mask, BitMask< unsigned int, 32 > hide_mask, BitMask< unsigned int, 32 > clear_mask); Description: Adjusts the hide/show bits of this particular node. These three parameters can be used to adjust the _draw_control_mask and _draw_show_mask independently, which work together to provide per-camera visibility for the node and its descendents. _draw_control_mask indicates the bits in _draw_show_mask that are significant. Each different bit corresponds to a different camera (and these bits are assigned via Camera::set_camera_mask()). Where _draw_control_mask has a 1 bit, a 1 bit in _draw_show_mask indicates the node is visible to that camera, and a 0 bit indicates the node is hidden to that camera. Where _draw_control_mask is 0, the node is hidden only if a parent node is hidden. The meaning of the three parameters is as follows: * Wherever show_mask is 1, _draw_show_mask and _draw_control_mask will be set 1. Thus, show_mask indicates the set of cameras to which the node should be shown. * Wherever hide_mask is 1, _draw_show_mask will be set 0 and _draw_control_mask will be set 1. Thus, hide_mask indicates the set of cameras from which the node should be hidden. * Wherever clear_mask is 1, _draw_control_mask will be set 0. Thus, clear_mask indicates the set of cameras from which the hidden state should be inherited from a parent.

asLight virtual Light *PandaNode::as_light(void); Description: Cross-casts the node to a Light pointer, if it is one of the four kinds of Light nodes, or returns NULL if it is not.

clearAttrib void PandaNode::clear_attrib(TypeHandle type); Description: Removes the render attribute of the given type from this node. This node, and the subgraph below, will now inherit the indicated render attribute from the nodes above this one.

clearBounds void PandaNode::clear_bounds(void); Description: Reverses the effect of a previous call to set_bounds(), and allows the node's bounding volume to be automatically computed once more based on the contents of the node.

clearEffect void PandaNode::clear_effect(TypeHandle type); Description: Removes the render effect of the given type from this node.

clearEffects void PandaNode::clear_effects(void); Description: Resets this node to have no render effects.

clearPythonTag void PandaNode::clear_python_tag(string const &key); Description: Removes the Python object defined for this key on this particular node. After a call to clear_python_tag(), has_python_tag() will return false for the indicated key.

clearState void PandaNode::clear_state(void); Description: Resets this node to leave the render state alone. Nodes at this level and below will once again inherit their render state unchanged from the nodes above this level.

clearTag void PandaNode::clear_tag(string const &key); Description: Removes the value defined for this key on this particular node. After a call to clear_tag(), has_tag() will return false for the indicated key.

clearTransform void PandaNode::clear_transform(void); Description: Resets the transform on this node to the identity transform.

copyChildren void PandaNode::copy_children(PandaNode *other); Description: Makes another instance of all the children of the other node, copying them to this node.

copySubgraph PointerTo< PandaNode > PandaNode::copy_subgraph(void) const; Description: Allocates and returns a complete copy of this PandaNode and the entire scene graph rooted at this PandaNode. Some data may still be shared from the original (e.g. vertex index tables), but nothing that will impede normal use of the PandaNode.

copyTags void PandaNode::copy_tags(PandaNode *other); HAVE_PYTHON Description: Copies all of the tags stored on the other node onto this node. If a particular tag exists on both nodes, the contents of this node's value is replaced by that of the other.

findChild int PandaNode::find_child(PandaNode *node) const; Description: Returns the index of the indicated child node, if it is a child, or -1 if it is not.

findParent int PandaNode::find_parent(PandaNode *node) const; Description: Returns the index of the indicated parent node, if it is a parent, or -1 if it is not.

findStashed int PandaNode::find_stashed(PandaNode *node) const; Description: Returns the index of the indicated stashed node, if it is a stashed child, or -1 if it is not.

getAllCameraMask static BitMask< unsigned int, 32 > PandaNode::get_all_camera_mask(void); Description: Returns a DrawMask that is appropriate for rendering to all cameras.

getAttrib RenderAttrib const *PandaNode::get_attrib(TypeHandle type) const; Description: Returns the render attribute of the indicated type, if it is defined on the node, or NULL if it is not. This checks only what is set on this particular node level, and has nothing to do with what render attributes may be inherited from parent nodes.

getBounds ConstPointerTo< BoundingVolume > PandaNode::get_bounds(void) const; Description: Returns the external bounding volume of this node: a bounding volume that contains the user bounding volume, the internal bounding volume, and all of the children's bounding volumes.

getChild PandaNode *PandaNode::get_child(int n) const; Description: Returns the nth child node of this node. See get_num_children().

getChildSort int PandaNode::get_child_sort(int n) const; Description: Returns the sort index of the nth child node of this node (that is, the number that was passed to add_child()). See get_num_children().

getClassType static TypeHandle PandaNode::get_class_type(void); Undocumented function.

getDrawControlMask BitMask< unsigned int, 32 > PandaNode::get_draw_control_mask(void) const; Description: Returns the set of bits in draw_show_mask that are considered meaningful. See adjust_draw_mask().

getDrawShowMask BitMask< unsigned int, 32 > PandaNode::get_draw_show_mask(void) const; Description: Returns the hide/show bits of this particular node. See adjust_draw_mask().

getEffect RenderEffect const *PandaNode::get_effect(TypeHandle type) const; Description: Returns the render effect of the indicated type, if it is defined on the node, or NULL if it is not.

getEffects RenderEffects const *PandaNode::get_effects(void) const; Description: Returns the complete RenderEffects that will be applied to this node.

getInternalBounds ConstPointerTo< BoundingVolume > PandaNode::get_internal_bounds(void) const; Description: Returns the node's internal bounding volume. This is the bounding volume around the node alone, without including children. If the user has called set_bounds(), it will be the specified bounding volume. Description: Returns the node's internal bounding volume. This is the bounding volume around the node alone, without including children.

getIntoCollideMask BitMask< unsigned int, 32 > PandaNode::get_into_collide_mask(void) const; Description: Returns the "into" collide mask for this node.

getLegalCollideMask virtual BitMask< unsigned int, 32 > PandaNode::get_legal_collide_mask(void) const; Description: Returns the subset of CollideMask bits that may be set for this particular type of PandaNode. For most nodes, this is 0; it doesn't make sense to set a CollideMask for most kinds of nodes. For nodes that can be collided with, such as GeomNode and CollisionNode, this returns all bits on.

getNetCollideMask BitMask< unsigned int, 32 > PandaNode::get_net_collide_mask(void) const; Description: Returns the union of all into_collide_mask() values set at CollisionNodes at this level and below.

getNetDrawControlMask BitMask< unsigned int, 32 > PandaNode::get_net_draw_control_mask(void) const; Description: Returns the set of bits in get_net_draw_show_mask() that have been explicitly set via adjust_draw_mask(), rather than implicitly inherited. A 1 bit in any position of this mask indicates that (a) this node has renderable children, and (b) some child of this node has made an explicit hide() or show_through() call for the corresponding bit.

getNetDrawShowMask BitMask< unsigned int, 32 > PandaNode::get_net_draw_show_mask(void) const; Description: Returns the union of all draw_show_mask values--of renderable nodes only--at this level and below. If any bit in this mask is 0, there is no reason to traverse below this node for a camera with the corresponding camera_mask. The bits in this mask that do not correspond to a 1 bit in the net_draw_control_mask are meaningless (and will be set to 1). For bits that *do* correspond to a 1 bit in the net_draw_control_mask, a 1 bit indicates that at least one child should be visible, while a 0 bit indicates that all children are hidden.

getNumChildren int PandaNode::get_num_children(void) const; Description: Returns the number of child nodes this node has. The order of the child nodes *is* meaningful and is based on the sort number that was passed to add_child(), and also on the order in which the nodes were added.

getNumParents int PandaNode::get_num_parents(void) const; Description: Returns the number of parent nodes this node has. If this number is greater than 1, the node has been multiply instanced. The order of the parent nodes is not meaningful and is not related to the order in which the node was instanced to them.

getNumStashed int PandaNode::get_num_stashed(void) const; Description: Returns the number of stashed nodes this node has. These are former children of the node that have been moved to the special stashed list via stash_child().

getOffClipPlanes ConstPointerTo< RenderAttrib > PandaNode::get_off_clip_planes(void) const; Description: Returns a ClipPlaneAttrib which represents the union of all of the clip planes that have been turned *off* at this level and below.

getOverallBit static BitMask< unsigned int, 32 > PandaNode::get_overall_bit(void); Description: Returns the special bit that, when specifically cleared in the node's DrawMask, indicates that the node is hidden to all cameras, regardless of the remaining DrawMask bits.

getParent PandaNode *PandaNode::get_parent(int n) const; Description: Returns the nth parent node of this node. See get_num_parents().

getPrevTransform TransformState const *PandaNode::get_prev_transform(void) const; Description: Returns the transform that has been set as this node's "previous" position. See set_prev_transform().

getPythonTag PyObject *PandaNode::get_python_tag(string const &key) const; Description: Retrieves the Python object that was previously set on this node for the particular key, if any. If no value has been previously set, returns None.

getStashed PandaNode *PandaNode::get_stashed(int n) const; Description: Returns the nth stashed node of this node. See get_num_stashed(). Description: Returns an object that can be used to walk through the list of stashed children of the node. When you intend to visit multiple children, using this is slightly faster than calling get_stashed() directly on the PandaNode, since this object keeps the PipelineCycler open the whole time. However, this object does not protect you from self-modifying loops (e.g. adding or removing stashed during traversal). Furthermore, if Panda is compiled with pipelining enabled, this method is compiled to behave exactly as get_stashed_copy(): it returns a copy. This is intended to reduce the risk of deadlocks.

getStashedSort int PandaNode::get_stashed_sort(int n) const; Description: Returns the sort index of the nth stashed node of this node (that is, the number that was passed to add_child()). See get_num_stashed().

getState RenderState const *PandaNode::get_state(void) const; Description: Returns the complete RenderState that will be applied to all nodes at this level and below, as set on this node. This returns only the RenderState set on this particular node, and has nothing to do with state that might be inherited from above.

getTag string PandaNode::get_tag(string const &key) const; Description: Retrieves the user-defined value that was previously set on this node for the particular key, if any. If no value has been previously set, returns the empty string.

getTransform TransformState const *PandaNode::get_transform(void) const; Description: Returns the transform that has been set on this particular node. This is not the net transform from the root, but simply the transform on this particular node.

hasAttrib bool PandaNode::has_attrib(TypeHandle type) const; Description: Returns true if there is a render attribute of the indicated type defined on this node, or false if there is not.

hasEffect bool PandaNode::has_effect(TypeHandle type) const; Description: Returns true if there is a render effect of the indicated type defined on this node, or false if there is not.

hasPythonTag bool PandaNode::has_python_tag(string const &key) const; Description: Returns true if a Python object has been defined on this node for the particular key (even if that object is None), or false if no object has been set.

hasTag bool PandaNode::has_tag(string const &key) const; Description: Returns true if a value has been defined on this node for the particular key (even if that value is the empty string), or false if no value has been set.

hasTags bool PandaNode::has_tags(void) const; HAVE_PYTHON Description: Returns true if the node has any tags (or any Python tags) at all, false if it has none.

isFinal bool PandaNode::is_final(void) const; Description: Returns the current state of the "final" flag. Initially, this flag is off (false), but it may be changed by an explicit call to set_final(). See set_final().

isGeomNode virtual bool PandaNode::is_geom_node(void) const; Description: A simple downcast check. Returns true if this kind of node happens to inherit from GeomNode, false otherwise. This is provided as a a faster alternative to calling is_of_type(GeomNode::get_class_type()), since this test is so important to rendering.

isLodNode virtual bool PandaNode::is_lod_node(void) const; Description: A simple downcast check. Returns true if this kind of node happens to inherit from LODNode, false otherwise. This is provided as a a faster alternative to calling is_of_type(LODNode::get_class_type()).

isOverallHidden bool PandaNode::is_overall_hidden(void) const; Description: Returns true if the node has been hidden to all cameras by clearing its overall bit.

listTags void PandaNode::list_tags(ostream &out, string const &separator = ("\n")) const; Description: Writes a list of all the tag keys assigned to the node to the indicated stream. Writes one instance of the separator following each key (but does not write a terminal separator). The value associated with each key is not written. This is mainly for the benefit of the realtime user, to see the list of all of the associated tag keys.

ls void PandaNode::ls(ostream &out, int indent_level) const; Description: Lists all the nodes at and below the current path hierarchically.

markBoundsStale void PandaNode::mark_bounds_stale(void) const; Description: Indicates that the bounding volume, or something that influences the bounding volume (or any of the other things stored in CDataBounds, like net_collide_mask), may have changed for this node, and that it must be recomputed. With no parameters, this means to iterate through all stages including and upstream of the current pipeline stage. This method is intended for internal use; usually it is not necessary for a user to call this directly. It will be called automatically by derived classes when appropriate.

output virtual void PandaNode::output(ostream &out) const; Description:

removeAllChildren void PandaNode::remove_all_children(void); Description: Removes all the children from the node at once, including stashed children. This can only be called from the top pipeline stage (i.e. from App).

removeChild void PandaNode::remove_child(int child_index); Description: Removes the nth child from the node. Description: Removes the indicated child from the node. Returns true if the child was removed, false if it was not already a child of the node. This will also successfully remove the child if it had been stashed.

removeStashed void PandaNode::remove_stashed(int child_index); Description: Removes the nth stashed child from the node.

replaceChild bool PandaNode::replace_child(PandaNode *orig_child, PandaNode *new_child); Description: Searches for the orig_child node in the node's list of children, and replaces it with the new_child instead. Returns true if the replacement is made, or false if the node is not a child.

resetPrevTransform void PandaNode::reset_prev_transform(void); Description: Resets the "previous" transform on this node to be the same as the current transform. This is not the same as clearing it to identity.

setAttrib void PandaNode::set_attrib(RenderAttrib const *attrib, int override = (0)); Description: Adds the indicated render attribute to the scene graph on this node. This attribute will now apply to this node and everything below. If there was already an attribute of the same type, it is replaced.

setBound void PandaNode::set_bound(BoundingVolume const *volume); A node has three bounding volumes: an "external" bounding volume that represents the node and all of its children, an "internal" bounding volume which represents only the node itself (and is usually empty, unless a specific node type sets it otherwise), and a "user" bounding volume which is specified by the user. We define set_bounds() and get_bounds() functions so that set_bounds() sets the user bounding volume, while get_bounds() returns the external bounding volume. Although it might seem strange and confusing to do this, this is actually the natural way the user thinks about nodes and bounding volumes. Description: Deprecated. Use set_bounds() instead.

setBounds void PandaNode::set_bounds(BoundingVolume const *volume); A node has three bounding volumes: an "external" bounding volume that represents the node and all of its children, an "internal" bounding volume which represents only the node itself (and is usually empty, unless a specific node type sets it otherwise), and a "user" bounding volume which is specified by the user. We define set_bounds() and get_bounds() functions so that set_bounds() sets the user bounding volume, while get_bounds() returns the external bounding volume. Although it might seem strange and confusing to do this, this is actually the natural way the user thinks about nodes and bounding volumes. Description: Resets the bounding volume so that it is the indicated volume. When it is explicitly set, the bounding volume will no longer be automatically computed according to the contents of the node itself, for nodes like GeomNodes and TextNodes that contain substance (but the bounding volume will still be automatically expanded to include its children). Call clear_bounds() if you would like to return the bounding volume to its default behavior later.

setEffect void PandaNode::set_effect(RenderEffect const *effect); Description: Adds the indicated render effect to the scene graph on this node. If there was already an effect of the same type, it is replaced.

setEffects void PandaNode::set_effects(RenderEffects const *effects); Description: Sets the complete RenderEffects that will be applied this node. This completely replaces whatever has been set on this node via repeated calls to set_attrib().

setFinal void PandaNode::set_final(bool flag); Description: Sets the "final" flag on this PandaNode. If this is true, than no bounding volume need be tested below it; a positive intersection with this node's bounding volume is deemed to be a positive intersection with all geometry inside. This is useful to quickly force a larger bounding volume around a node when the GeomNodes themselves are inaccurate for some reason, without forcing a recompute of every nested bounding volume. It's also helpful when the bounding volume is tricked by some special properties, like billboards, that may move geometry out of its bounding volume otherwise.

setIntoCollideMask void PandaNode::set_into_collide_mask(BitMask< unsigned int, 32 > mask); Description: Sets the "into" CollideMask. This specifies the set of bits that must be shared with a CollisionNode's "from" CollideMask in order for the CollisionNode to detect a collision with this particular node. The actual CollideMask that will be set is masked by the return value from get_legal_collide_mask(). Thus, the into_collide_mask cannot be set to anything other than nonzero except for those types of nodes that can be collided into, such as CollisionNodes and GeomNodes.

setOverallHidden void PandaNode::set_overall_hidden(bool overall_hidden); Description: Sets or clears the hidden flag. When the hidden flag is true, the node and all of its children are invisible to all cameras, regardless of the setting of any draw masks. Setting the hidden flag to false restores the previous visibility as established by the draw masks. This actually works by twiddling the reserved _overall_bit in the node's draw mask, which has special meaning.

setPrevTransform void PandaNode::set_prev_transform(TransformState const *transform); Description: Sets the transform that represents this node's "previous" position, one frame ago, for the purposes of detecting motion for accurate collision calculations.

setPythonTag void PandaNode::set_python_tag(string const &key, PyObject *value); Description: Associates an arbitrary Python object with a user-defined key which is stored on the node. This is similar to set_tag(), except it can store any Python object instead of just a string. However, the Python object is not recorded to a bam file. Each unique key stores a different string value. There is no effective limit on the number of different keys that may be stored or on the length of any one key's value.

setState void PandaNode::set_state(RenderState const *state); Description: Sets the complete RenderState that will be applied to all nodes at this level and below. (The actual state that will be applied to lower nodes is based on the composition of RenderStates from above this node as well). This completely replaces whatever has been set on this node via repeated calls to set_attrib().

setTag void PandaNode::set_tag(string const &key, string const &value); Description: Associates a user-defined value with a user-defined key which is stored on the node. This value has no meaning to Panda; but it is stored indefinitely on the node until it is requested again. Each unique key stores a different string value. There is no effective limit on the number of different keys that may be stored or on the length of any one key's value.

setTransform void PandaNode::set_transform(TransformState const *transform); Description: Sets the transform that will be applied to this node and below. This defines a new coordinate space at this point in the scene graph and below.

stashChild bool PandaNode::stash_child(PandaNode *child_node); Description: Stashes the indicated child node. This removes the child from the list of active children and puts it on a special list of stashed children. This child node no longer contributes to the bounding volume of the PandaNode, and is not visited in normal traversals. It is invisible and uncollidable. The child may later be restored by calling unstash_child(). This function returns true if the child node was successfully stashed, or false if it was not a child of the node in the first place (e.g. it was previously stashed). This can only be called from the top pipeline stage (i.e. from App).

stealChildren void PandaNode::steal_children(PandaNode *other); Description: Moves all the children from the other node onto this node.

unstashChild bool PandaNode::unstash_child(PandaNode *child_node); Description: Returns the indicated stashed node to normal child status. This removes the child from the list of stashed children and puts it on the normal list of active children. This child node once again contributes to the bounding volume of the PandaNode, and will be visited in normal traversals. It is visible and collidable. This function returns true if the child node was successfully stashed, or false if it was not a child of the node in the first place (e.g. it was previously stashed). This can only be called from the top pipeline stage (i.e. from App).

write virtual void PandaNode::write(ostream &out, int indent_level) const; Description:

getClassType static TypeHandle TypedWritable::get_class_type(void); Undocumented function.

getBestParentFromSet int TypedObject::get_best_parent_from_Set(set< int > const &) const; Description: Returns true if the current object is the indicated type exactly.

getClassType static TypeHandle TypedObject::get_class_type(void); Undocumented function.

getType virtual TypeHandle TypedObject::get_type(void) const = 0; Derived classes should override this function to return get_class_type().

getTypeIndex int TypedObject::get_type_index(void) const; Description: Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index().

isExactType bool TypedObject::is_exact_type(TypeHandle handle) const; Description: Returns true if the current object is the indicated type exactly.

isOfType bool TypedObject::is_of_type(TypeHandle handle) const; Description: Returns true if the current object is or derives from the indicated type.

clearName void Namable::clear_name(void); Description: Resets the Namable's name to empty.

getClassType static TypeHandle Namable::get_class_type(void); Undocumented function.

getName string const &Namable::get_name(void) const; Description:

hasName bool Namable::has_name(void) const; Description: Returns true if the Namable has a nonempty name set, false if the name is empty.

operator = Namable &Namable::operator =(Namable const &other); Description:

output void Namable::output(ostream &out) const; In the absence of any definition to the contrary, outputting a Namable will write out its name. Description: Outputs the Namable. This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

setName void Namable::set_name(string const &name); Description:

getClassType static TypeHandle ReferenceCount::get_class_type(void); Undocumented function.

getRefCount int ReferenceCount::get_ref_count(void) const; Description: Returns the current reference count.

ref void ReferenceCount::ref(void) const; Description: Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

testRefCountIntegrity bool ReferenceCount::test_ref_count_integrity(void) const; Description: Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise.

unref bool ReferenceCount::unref(void) const; Description: Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete(). User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it. The return value is true if the new reference count is nonzero, false if it is zero.
