RefCounted

#include <Ultralight/RefPtr.h>

Overview

Interface for all ref-counted objects that will be managed using the RefPtr<> smart pointer.

Inheritance diagram for RefCounted:

Public Member Functions
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.
virtual WeakControlBlock *	weak_control_block () const
	Get the control block used to track weak references to this object.

Protected Member Functions
virtual	~RefCounted ()

Member Function Documentation

AddRef()

virtual void AddRef ( ) const

pure virtual

Increment the reference count (thread-safe).

ref_count()

virtual int ref_count ( ) const

pure virtual

Get the current reference count.

Release()

virtual void Release ( ) const

pure virtual

Decrement the reference count (thread-safe).

The object is destroyed when the count reaches zero.

weak_control_block()

virtual WeakControlBlock * weak_control_block ( ) const

inlinevirtual

Get the control block used to track weak references to this object.

Returns

Returns the control block, or nullptr if the concrete type does not support weak references (only types derived from WeakRefCounted do).

Note

This is internal bookkeeping for WeakPtr; you should never need to call it directly.

Reimplemented in WeakRefCounted.
