This class specializes ReferenceCount to add an additional counter, called node_ref_count, for the purposes of counting the number of times the object is referenced by a "node", whatever that may mean in context.
The new methods node_ref() and node_unref() automatically increment and decrement the primary reference count as well. There also exists a NodePointerTo<> class to maintain the node_ref counters automatically.
See also CachedTypedWritableReferenceCount, which is similar in principle, as well as NodeCachedReferenceCount, which combines both of these.
| static TypeHandle getClassType | ( | ) | [static] |
Reimplemented from ReferenceCount.
| int getNodeRefCount | ( | ) |
Returns the current reference count.
| nodeRef | ( | ) |
Explicitly increments the node reference count and the normal reference count simultaneously.
| bool nodeUnref | ( | ) |
Explicitly decrements the node 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.
| bool testRefCountIntegrity | ( | ) |
Does some easy checks to make sure that the reference count isn't completely bogus.
Reimplemented from ReferenceCount.
