Detailed Description

template<class Base>
class RefCountObj< Base >

Another kind of proxy, similar to RefCountProxy.

This one works by inheriting from the indicated base type, giving it an is-a relation instead of a has-a relation. As such, it's a little more robust, but only works when the base type is, in fact, a class.

Member Function Documentation

template<class Base> TypeHandle RefCountObj< Base >::get_class_type (  void   )  [inline, static]

Reimplemented from ReferenceCount. Definition at line 151 of file referenceCount.h.

int ReferenceCount::get_ref_count (   )  const [inline, inherited]

Returns the current reference count. Definition at line 183 of file referenceCount.I. Referenced by RenderState::determine_bin_index(), RenderEffects::determine_show_bounds(), FontPool::ns_garbage_collect(), TexturePool::ns_garbage_collect(), MaterialPool::ns_get_material(), and TexturePool::ns_release_texture().

template<class Base> void RefCountObj< Base >::init_type (  void   )  [static]

Reimplemented from ReferenceCount. Definition at line 491 of file referenceCount.I.

int ReferenceCount::ref (   )  const [inline, 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. The return value is the new reference count. Definition at line 225 of file referenceCount.I. Referenced by ClientDevice::ClientDevice(), EggGroupNode::find_textures(), EggGroupNode::r_apply_texmats(), EggGroupNode::r_flatten_transforms(), and EggGroupNode::reverse_vertex_ordering().

void ReferenceCount::test_ref_count_integrity (   )  const [inline, inherited]

Does some easy checks to make sure that the reference count isn't completely bogus. Definition at line 328 of file referenceCount.I. References INLINE. Referenced by EggNode::determine_bin(), and ReferenceCount::~ReferenceCount().

int ReferenceCount::unref (   )  const [inline, 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; plus, we don't have a virtual destructor anyway.) 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 the new reference count. Definition at line 293 of file referenceCount.I. References INLINE. Referenced by RenderState::determine_bin_index(), and RenderEffects::determine_show_bounds().
