Public Member Functions | |
const RenderAttrib | addStage (TextureStage stage, const TransformState transform, int override) |
Returns a new TexMatrixAttrib just like this one, with the indicated transform for the given stage. | |

Returns the union of the Geom::GeomRendering bits that will be required once this TexMatrixAttrib is applied to a geom which includes the indicated geom_rendering bits. | |
const LMatrix4 | getMat () |
Returns the transformation matrix associated with the default texture stage. | |
const LMatrix4 | getMat (TextureStage stage) |
Returns the transformation matrix associated with the indicated texture stage, or identity matrix if nothing is associated with the indicated stage. | |

int | getOverride (TextureStage stage) |
Returns the override value associated with the indicated stage. | |

Returns the transformation associated with the indicated texture stage, or identity matrix if nothing is associated with the indicated stage. | |
bool | hasStage (TextureStage stage) |
Returns true if there is a transform associated with the indicated stage, or false otherwise (in which case get_transform(stage) will return the identity transform). | |
bool | isEmpty () |
Returns true if no stages are defined in the TexMatrixAttrib, false if at least one is. | |
const RenderAttrib | removeStage (TextureStage stage) |
Returns a new TexMatrixAttrib just like this one, with the indicated stage removed. | |
![]() | |
int | compareTo (const RenderAttrib other) |
Provides an arbitrary ordering among all unique RenderAttribs, so we can store the essentially different ones in a big set and throw away the rest. | |
const RenderAttrib | compose (const RenderAttrib other) |
Returns a new RenderAttrib object that represents the composition of this attrib with the other attrib. | |
int | getHash () |
Returns a suitable hash value for phash_map. | |
int | getSlot () |
const RenderAttrib | getUnique () |
Returns the pointer to the unique RenderAttrib in the cache that is equivalent to this one. | |
const RenderAttrib | invertCompose (const RenderAttrib other) |
Returns a new RenderAttrib object that represents the composition of the inverse of this attrib with the other attrib. | |
bool | lowerAttribCanOverride () |
Intended to be overridden by derived RenderAttrib types to specify how two consecutive RenderAttrib objects of the same type interact. | |

write (Ostream out, int indent_level) | |
![]() | |
object | __reduce__ () |
object | __reduce_persist__ (object pickler) |
VectorUchar | encodeToBamStream () |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a bytes object. | |
bool | encodeToBamStream (VectorUchar data, BamWriter writer) |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string. | |
fillin (DatagramIterator scan, BamReader manager) | |
This internal function is intended to be called by each class's make_from_bam() method to read in all of the relevant data from the BamFile for the new object. | |
UpdateSeq | getBamModified () |
Returns the current bam_modified counter. | |
markBamModified () | |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. | |
![]() | |
TypeHandle | getType () |
int | getTypeIndex () |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. | |
bool | isExactType (TypeHandle handle) |
Returns true if the current object is the indicated type exactly. | |
bool | isOfType (TypeHandle handle) |
Returns true if the current object is or derives from the indicated type. | |
![]() | |
int | getRefCount () |
Returns the current reference count. | |
ref () | |
Explicitly increments the reference count. | |
bool | testRefCountIntegrity () |
Does some easy checks to make sure that the reference count isn't completely bogus. | |
bool | testRefCountNonzero () |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. | |
bool | unref () |
Explicitly decrements the reference count. | |
