Public Member Functions | |
unsigned int | getChannels () |
Returns the mask of color channels that are enabled by this attrib. More... | |
![]() | |
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. More... | |
const RenderAttrib | compose (const RenderAttrib other) |
Returns a new RenderAttrib object that represents the composition of this attrib with the other attrib. More... | |
int | getHash () |
Returns a suitable hash value for phash_map. More... | |
int | getSlot () |
const RenderAttrib | getUnique () |
Returns the pointer to the unique RenderAttrib in the cache that is equivalent to this one. More... | |
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. More... | |
bool | lowerAttribCanOverride () |
Intended to be overridden by derived RenderAttrib types to specify how two consecutive RenderAttrib objects of the same type interact. More... | |
output (Ostream out) | |
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. More... | |
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. More... | |
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. More... | |
UpdateSeq | getBamModified () |
Returns the current bam_modified counter. More... | |
markBamModified () | |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. More... | |
![]() | |
TypeHandle | getType () |
int | getTypeIndex () |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. More... | |
bool | isExactType (TypeHandle handle) |
Returns true if the current object is the indicated type exactly. More... | |
bool | isOfType (TypeHandle handle) |
Returns true if the current object is or derives from the indicated type. More... | |
![]() | |
int | getRefCount () |
Returns the current reference count. More... | |
ref () | |
Explicitly increments the reference count. More... | |
bool | testRefCountIntegrity () |
Does some easy checks to make sure that the reference count isn't completely bogus. More... | |
bool | testRefCountNonzero () |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. More... | |
bool | unref () |
Explicitly decrements the reference count. More... | |

static const RenderAttrib | make (unsigned int channels) |
Constructs a new ColorWriteAttrib object. More... | |
static const RenderAttrib | makeDefault () |

Ensures that the cache is still stored in sorted order. More... | |
![]() | |
static TypedWritableReferenceCount | decodeFromBamStream (VectorUchar data, BamReader reader) |
Reads the bytes created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on those bytes. More... | |

The current reference count. More... | |
Enables or disables writing to the color buffer.
This is primarily useful for certain special effects in which it is important to write to the depth buffer without affecting the color buffer.
