Methods of ReferenceCount:

getClassType
static TypeHandle NodeReferenceCount::get_class_type(void);

Undocumented function.

getNodeRefCount
int NodeReferenceCount::get_node_ref_count(void) const;

Description: Returns the current reference count.

nodeRef
void NodeReferenceCount::node_ref(void) const;

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

nodeUnref
bool NodeReferenceCount::node_unref(void) const;

Description: 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.

testRefCountIntegrity
bool NodeReferenceCount::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 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().
