Static Public Member Functions | |
static TypedWritableReferenceCount | decodeFromBamStream (string data, BamReader reader) |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on that string. | |
static TypedWritableReferenceCount | decodeFromBamStream (string data) |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on that string. | |
static TypeHandle | getClassType () |
An animation channel that accepts a matrix each frame from some dynamic input provided by code.
This object operates in two modes: in explicit mode, the programmer should call set_value() each frame to indicate the new value; in implicit mode, the programmer should call set_value_node() to indicate the node whose transform will be copied to the joint each frame.
clearName | ( | ) | [inherited] |
Resets the Namable's name to empty.
Reimplemented in AsyncTask.
static TypedWritableReferenceCount decodeFromBamStream | ( | string | data, |
BamReader | reader | ||
) | [static, inherited] |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on that string.
Returns NULL on error.
This method is intended to replace decode_raw_from_bam_stream() when you know the stream in question returns an object of type TypedWritableReferenceCount, allowing for easier reference count management. Note that the caller is still responsible for maintaining the reference count on the return value.
static TypedWritableReferenceCount decodeFromBamStream | ( | string | data | ) | [static, inherited] |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on that string.

string encodeToBamStream | ( | ) | [inherited] |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a string string.
Returns empty string on failure.
This is a convenience method particularly useful for cases when you are only serializing a single object. If you have many objects to process, it is more efficient to use the same BamWriter to serialize all of them together.
bool encodeToBamStream | ( | basic_stringchar | data, |
BamWriter | writer | ||
) | [inherited] |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string.
Returns true on success, false on failure.

AnimGroup findChild | ( | string | name | ) | [inherited] |
Returns the first descendant found with the indicated name, or NULL if no such descendant exists.
This method searches the entire graph beginning at this AnimGroup; see also get_child_named().
UpdateSeq getBamModified | ( | ) | [inherited] |
Returns the current bam_modified counter.
This counter is normally incremented automatically whenever the object is modified.
AnimGroup getChildNamed | ( | string | name | ) | [inherited] |
Returns the first child found with the indicated name, or NULL if no such child exists.
This method searches only the children of this particular AnimGroup; it does not recursively search the entire graph. See also find_child().
list getChildren | ( | ) | [inherited] |
static TypeHandle getClassType | ( | ) | [static] |
Reimplemented from AnimChannelACMatrixSwitchType.
string getName | ( | ) | [inherited] |
Reimplemented in DynamicTextFont.
int getNumChildren | ( | ) | [inherited] |
Returns the number of child nodes of the group.
int getRefCount | ( | ) | [inherited] |
Returns the current reference count.
TypeHandle getType | ( | ) | [inherited] |
Reimplemented from TypedObject.
int getTypeIndex | ( | ) | [inherited] |
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().
PandaNode getValueNode | ( | ) |
Returns the node that was set via set_value_node(), if any.
TransformState const getValueTransform | ( | ) |
Returns the explicit TransformState value that was set via set_value(), if any.
TypeHandle getValueType | ( | ) | [inherited] |
bool hasName | ( | ) | [inherited] |
Returns true if the Namable has a nonempty name set, false if the name is empty.
bool isExactType | ( | TypeHandle | handle | ) | [inherited] |
Returns true if the current object is the indicated type exactly.
bool isOfType | ( | TypeHandle | handle | ) | [inherited] |
Returns true if the current object is or derives from the indicated type.
markBamModified | ( | ) | [inherited] |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams.
This should normally not need to be called by user code; it should be called internally when the object has been changed in a way that legitimately requires its retransmission to any connected clients.
output | ( | ostream | out | ) | [inherited] |
Writes a one-line description of the group.
Reimplemented from Namable.
PyObject reduce | ( | PyObject | self | ) | [inherited] |
This special Python method is implement to provide support for the pickle module.
This hooks into the native pickle and cPickle modules, but it cannot properly handle self-referential BAM objects.
PyObject reducePersist | ( | PyObject | self, |
PyObject | pickler | ||
) | [inherited] |
This special Python method is implement to provide support for the pickle module.
This is similar to __reduce__, but it provides additional support for the missing persistent-state object needed to properly support self-referential BAM objects written to the pickle stream. This hooks into the pickle and cPickle modules implemented in direct/src/stdpy.
ref | ( | ) | [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.
setValue | ( | TransformState const | value | ) |
Explicitly sets the matrix value, using the indicated TransformState object as a convenience.
setValue | ( | Mat4 const | value | ) |
Explicitly sets the matrix value.
setValueNode | ( | PandaNode | node | ) |
Specifies a node whose transform will be queried each frame to implicitly specify the transform of this joint.
bool testRefCountIntegrity | ( | ) | [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.
bool testRefCountNonzero | ( | ) | [inherited] |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus.
Returns true if ok, false otherwise.
bool unref | ( | ) | [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, and GeomVertexFormat.
