getClassType
static TypeHandle TypedReferenceCount::get_class_type(void);

Undocumented function.

getBestParentFromSet
int TypedObject::get_best_parent_from_Set(set< int > const &) const;

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

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().

Undocumented function.

getRefCount
int ReferenceCount::get_ref_count(void) const;

Description: Returns the current reference count.

ref
int 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.
The return value is the new reference count.

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.

unref
int 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().
