static TypeHandle getClassType ( ) [static]

Reimplemented from TypedReferenceCount.

int getRefCount ( ) [inherited]

Returns the current reference count.

TypeHandle getType ( ) [inherited]

Reimplemented in AnimChannelBase.

int getTypeIndex ( ) [inherited]

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().

bool isExactType ( TypeHandle  handle) [inherited]

Returns true if the current object is the indicated type exactly.

bool isOfType ( TypeHandle  handle) [inherited]

Returns true if the current object is or derives from the indicated type.

ref ( ) [inherited]

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.

bool testRefCountIntegrity ( ) [inherited]

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

Returns true if ok, false otherwise.

Reimplemented in NodeReferenceCount, CachedTypedWritableReferenceCount, and NodeCachedReferenceCount.

bool testRefCountNonzero ( ) [inherited]

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

Returns true if ok, false otherwise.

bool unref ( ) [inherited]

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.) 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.

Reimplemented in GeomVertexArrayFormat, and GeomVertexFormat.
