Constants in RenderAttrib:

addStage
ConstPointerTo< RenderAttrib > TexMatrixAttrib::add_stage(TextureStage *stage, TransformState const *transform) const;

Description: Returns a new TexMatrixAttrib just like this one, with the indicated transform for the given stage. If this stage already exists, its transform is replaced.

getClassType
static TypeHandle TexMatrixAttrib::get_class_type(void);

Undocumented function.

getGeomRendering
int TexMatrixAttrib::get_geom_rendering(int geom_rendering) const;

Description: 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.

getMat
LMatrix4f const &TexMatrixAttrib::get_mat(void) const;

Description: Returns the transformation matrix associated with the default texture stage.
Description: Returns the transformation matrix associated with the named texture stage, or identity matrix if nothing is associated with the indicated stage.

getNumStages
int TexMatrixAttrib::get_num_stages(void) const;

Description: Returns the number of stages that are represented by this attrib.

getStage
TextureStage *TexMatrixAttrib::get_stage(int n) const;

Description: Returns the nth stage that is represented by this attrib. The TextureStages are in no particular order.

getTransform
ConstPointerTo< TransformState > TexMatrixAttrib::get_transform(TextureStage *stage) const;

Description: Returns the transformation associated with the named texture stage, or identity matrix if nothing is associated with the indicated stage.

hasStage
bool TexMatrixAttrib::has_stage(TextureStage *stage) const;

Description: 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).

isEmpty
bool TexMatrixAttrib::is_empty(void) const;

Description: Returns true if no stages are defined in the TexMatrixAttrib, false if at least one is.

make
static ConstPointerTo< RenderAttrib > TexMatrixAttrib::make(void);

Description: Constructs a TexMatrixAttrib that applies no stages at all.
Description: Constructs a TexMatrixAttrib that applies the indicated matrix to the default texture stage. This interface is deprecated.
Description: Constructs a TexMatrixAttrib that applies the indicated transform to the named texture stage.

removeStage
ConstPointerTo< RenderAttrib > TexMatrixAttrib::remove_stage(TextureStage *stage) const;

Description: Returns a new TexMatrixAttrib just like this one, with the indicated stage removed.

compareTo
int RenderAttrib::compare_to(RenderAttrib const &other) const;

Description: 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.
This method is not needed outside of the RenderAttrib class because all equivalent RenderAttrib objects are guaranteed to share the same pointer; thus, a pointer comparison is always sufficient.

getClassType
static TypeHandle RenderAttrib::get_class_type(void);

Undocumented function.

getNumAttribs
static int RenderAttrib::get_num_attribs(void);

Description: Returns the total number of unique RenderAttrib objects allocated in the world. This will go up and down during normal operations.

listAttribs
static void RenderAttrib::list_attribs(ostream &out);

Description: Lists all of the RenderAttribs in the cache to the output stream, one per line. This can be quite a lot of output if the cache is large, so be prepared.

output
virtual void RenderAttrib::output(ostream &out) const;

Description:

validateAttribs
static bool RenderAttrib::validate_attribs(void);

Description: Ensures that the cache is still stored in sorted order. Returns true if so, false if there is a problem (which implies someone has modified one of the supposedly-const RenderAttrib objects).

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

Description:

getClassType
static TypeHandle TypedWritableReferenceCount::get_class_type(void);

Undocumented function.

getClassType
static TypeHandle TypedWritable::get_class_type(void);

Undocumented function.

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.

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.

testRefCountNonzero
bool ReferenceCount::test_ref_count_nonzero(void) const;

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