WeakRefCounted

#include <Ultralight/RefPtr.h>

Overview

Interface for ref-counted objects that can additionally be observed via the WeakPtr<> smart pointer.

Types deriving this interface support weak references: a WeakPtr can observe the object's lifetime without owning it. WeakPtr<T> requires T to derive WeakRefCounted; using it with a plain RefCounted type is a compile error.

Public Member Functions inherited from RefCounted
virtual void	AddRef () const =0
	Increment the reference count (thread-safe).
virtual void	Release () const =0
	Decrement the reference count (thread-safe).
virtual int	ref_count () const =0
	Get the current reference count.
