Constants in RenderAttrib:

addStage
ConstPointerTo< RenderAttrib > TexGenAttrib::add_stage(TextureStage *stage, RenderAttrib::TexGenMode mode) const;

Description: Returns a new TexGenAttrib just like this one, with the indicated generation mode for the given stage. If this stage already exists, its mode is replaced.
This variant also accepts source_name and light, which are only meaningful if mode is M_light_vector.
This variant also accepts constant_value, which is only meaningful if mode is M_constant.

getClassType
static TypeHandle TexGenAttrib::get_class_type(void);

Undocumented function.

getConstantValue
LPoint3f const &TexGenAttrib::get_constant_value(TextureStage *stage) const;

Description: Returns the constant value associated with the named texture stage. This is only meaningful if the mode is M_constant.

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

Description: Returns the union of the Geom::GeomRendering bits that will be required once this TexGenAttrib is applied to a geom which includes the indicated geom_rendering bits.

getLight
NodePath TexGenAttrib::get_light(TextureStage *stage) const;

Description: Returns the Light associated with the named texture stage, or the empty NodePath if no light is associated with the indicated stage. This is only meaningful if the mode is M_light_vector.

getMode
RenderAttrib::TexGenMode TexGenAttrib::get_mode(TextureStage *stage) const;

Description: Returns the generation mode associated with the named texture stage, or M_off if nothing is associated with the indicated stage.

getSourceName
string TexGenAttrib::get_source_name(TextureStage *stage) const;

Description: Returns the source name associated with the named texture stage, or the empty string if no name is associated with the indicated stage. This is only meaningful if the mode is M_light_vector, in which case it indicates the name of the source texture coordinate set from which the tangent and binormal are derived.

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

Description: Returns true if there is a mode associated with the indicated stage, or false otherwise (in which case get_transform(stage) will return M_off).

isEmpty
bool TexGenAttrib::is_empty(void) const;

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

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

Description: Constructs a TexGenAttrib that generates no stages at all.
Description: Constructs a TexGenAttrib that generates just the indicated stage.

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

Description: Returns a new TexGenAttrib 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.
