Member Function Documentation

void Namable::clear_name ( ) [inline, inherited]

Resets the Namable's name to empty.

Reimplemented in AsyncTask.

Definition at line 64 of file namable.I.

bool ReferenceCount::do_test_ref_count_integrity ( ) const [protected, inherited]

Does some easy checks to make sure that the reference count isn't completely bogus.

Returns true if ok, false otherwise.

Reimplemented in NodeReferenceCount, CachedTypedWritableReferenceCount, and NodeCachedReferenceCount.

Definition at line 29 of file referenceCount.cxx.

Referenced by ReferenceCount::do_test_ref_count_nonzero(), and ReferenceCount::test_ref_count_integrity().

bool ReferenceCount::do_test_ref_count_nonzero ( ) const [protected, inherited]

Returns true if the reference count is nonzero, false otherwise.

Definition at line 56 of file referenceCount.cxx.

References ReferenceCount::do_test_ref_count_integrity().

Referenced by ReferenceCount::test_ref_count_nonzero().

void MaxNodeDesc::from_INode ( INode *  max_node)

Indicates an associated between the MaxNodeDesc and some Max Node instance.

Definition at line 58 of file maxNodeDesc.cxx.

Referenced by MaxNodeTree::build_joint(), and MaxNodeTree::build_node().

INode * MaxNodeDesc::get_max_node ( ) const

Returns the INode associated with this node.

It is an error to call this unless has_max_node() returned true.

Definition at line 105 of file maxNodeDesc.cxx.

int ReferenceCount::get_ref_count ( ) const [inline, inherited]
WeakReferenceList * ReferenceCount::get_weak_list ( ) const [inline, inherited]

Returns the WeakReferenceList associated with this ReferenceCount object.

If there has never been a WeakReferenceList associated with this object, creates one now.

Definition at line 307 of file referenceCount.I.

Referenced by ReferenceCount::weak_ref().

bool MaxNodeDesc::has_max_node ( ) const

Returns true if a Max INode has been associated with this node, false otherwise.

Definition at line 93 of file maxNodeDesc.cxx.

bool Namable::has_name ( ) const [inline, inherited]
bool ReferenceCount::has_weak_list ( ) const [inline, inherited]

Returns true if this particular ReferenceCount object has a WeakReferenceList created, false otherwise.

In general, this will be true if there was ever a WeakPointerTo created for this object (even if there is not any for it now).

Definition at line 294 of file referenceCount.I.

Referenced by ReferenceCount::weak_unref().

bool MaxNodeDesc::is_joint ( ) const

Returns true if the node should be treated as a joint by the converter.

Definition at line 126 of file maxNodeDesc.cxx.

Referenced by MaxNodeTree::get_egg_group(), and MaxNodeTree::get_egg_table().

bool MaxNodeDesc::is_joint_parent ( ) const

Returns true if the node is the parent or ancestor of a joint.

Definition at line 137 of file maxNodeDesc.cxx.

bool MaxNodeDesc::is_node_joint ( ) const

Returns true if the node is the parent or ancestor of a joint.

Definition at line 148 of file maxNodeDesc.cxx.

Referenced by MaxNodeTree::build_node(), and MaxNodeTree::find_joint().

void ReferenceCount::local_object ( ) [inline, inherited]

This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.

This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

Definition at line 276 of file referenceCount.I.

Referenced by PGTop::cull_callback(), BoundingSphere::extend_by_hexahedron(), AsyncTaskManager::find_task(), AsyncTaskManager::find_tasks(), and AsyncTaskManager::find_tasks_matching().

void Namable::output ( ostream &  out) const [inline, inherited]
void ReferenceCount::ref ( ) const [inline, inherited]

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.

Definition at line 179 of file referenceCount.I.

References ReferenceCount::test_ref_count_integrity().

Referenced by CachedTypedWritableReferenceCount::cache_ref(), TypedWritable::decode_raw_from_bam_stream(), NodeCachedReferenceCount::node_ref(), NodeReferenceCount::node_ref(), BamCacheRecord::set_data(), CullableObject::set_draw_callback(), and ModelRoot::set_reference().

bool ReferenceCount::test_ref_count_integrity ( ) const [inline, inherited]
bool ReferenceCount::test_ref_count_nonzero ( ) const [inline, inherited]

Does some easy checks to make sure that the reference count isn't zero, or completely bogus.

Returns true if ok, false otherwise.

Definition at line 252 of file referenceCount.I.

References ReferenceCount::do_test_ref_count_nonzero().

Referenced by CopyOnWritePointer::test_ref_count_nonzero().

bool ReferenceCount::unref ( ) const [inline, virtual, inherited]

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.) 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.

Reimplemented in GeomVertexArrayFormat, GeomVertexFormat, InternalName, RenderAttrib, RenderEffects, RenderState, and TransformState.

void ReferenceCount::weak_ref ( WeakPointerToVoid ptv) [inline, inherited]

Adds the indicated PointerToVoid as a weak reference to this object.

Removes the indicated PointerToVoid as a weak reference to this object.

It must have previously been added via a call to weak_ref().
