addBlend
int TransformBlendTable::add_blend(TransformBlend const &blend);

Description: Adds a new blend to the table, and returns its index number. If there is already an identical blend in the table, simply returns that number instead.

getBlend
TransformBlend const &TransformBlendTable::get_blend(int n) const;

Description: Returns the nth blend in the table.

getClassType
static TypeHandle TransformBlendTable::get_class_type(void);

Undocumented function.

getMaxSimultaneousTransforms
int TransformBlendTable::get_max_simultaneous_transforms(void) const;

Description: Returns the maximum number of unique VertexTransform objects that are applied to any one vertex simultaneously. This is the same limit reflected by GraphicsStateGuardian::get_max_vertex_transforms().

getModified
UpdateSeq TransformBlendTable::get_modified(Thread *current_thread) const;

Description: Returns a counter which is guaranteed to increment at least when any TransformBlends within the table have changed.

getNumBlends
int TransformBlendTable::get_num_blends(void) const;

Description: Returns the total number of different blend combinations in the table.

getNumTransforms
int TransformBlendTable::get_num_transforms(void) const;

Description: Returns the number of unique VertexTransform objects represented in the table. This will correspond to the size of the TransformTable object that would represent the same table. This is also the same limit reflected by GraphicsStateGuardian::get_max_vertex_transform_indices().

getRows
SparseArray const &TransformBlendTable::get_rows(void) const;

Description: Returns the subset of rows (vertices) in the associated GeomVertexData that this TransformBlendTable actually affects.

modifyRows
SparseArray &TransformBlendTable::modify_rows(void);

Description: Returns a modifiable reference to the SparseArray that specifies the subset of rows (vertices) in the associated GeomVertexData that this TransformBlendTable actually affects.

operator =
void TransformBlendTable::operator =(TransformBlendTable const &copy);

Description:

removeBlend
void TransformBlendTable::remove_blend(int n);

Description: Removes the blend at the nth position.

setBlend
void TransformBlendTable::set_blend(int n, TransformBlend const &blend);

Description: Replaces the blend at the nth position with the indicated value.

setRows
void TransformBlendTable::set_rows(SparseArray const &rows);

Description: Specifies the subset of rows (vertices) in the associated GeomVertexData that this TransformBlendTable actually affects.

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

Description:

getClassType
static TypeHandle CopyOnWriteObject::get_class_type(void);

Undocumented function.

cacheRef
void CachedTypedWritableReferenceCount::cache_ref(void) const;

Description: Explicitly increments the cache reference count and the normal reference count simultaneously.

cacheUnref
bool CachedTypedWritableReferenceCount::cache_unref(void) const;

Description: Explicitly decrements the cache reference count and the normal reference count simultaneously.
The return value is true if the new reference count is nonzero, false if it is zero.

getCacheRefCount
int CachedTypedWritableReferenceCount::get_cache_ref_count(void) const;

Description: Returns the current reference count.

getClassType
static TypeHandle CachedTypedWritableReferenceCount::get_class_type(void);

Undocumented function.

testRefCountIntegrity
bool CachedTypedWritableReferenceCount::test_ref_count_integrity(void) const;

Description: Does some easy checks to make sure that the reference count isn't completely bogus.

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().
