This is a trivial class returned by PartBundleNode.get_bundle().
Its purpose is to hold the actual PartBundle pointer contained within the PartBundleNode, so that scene graph flatten operations can safely combine or duplicate PartBundles as necessary without affecting high-level bundle operations.
The high-level Actor class defined in direct/src/actor, for instance, will store a list of PartBundleHandles instead of on actual PartBundles, so that it will be immune to changes from these flatten operations.

int getRefCount | ( | ) | [inherited] |
Returns the current reference count.
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.
setBundle | ( | PartBundle | bundle | ) |
Changes the actual PartBundle embedded within the handle.
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.
