Detailed Description

RefCountingObject is a base class for classes that must maintain a thread-safe reference count.

Constructor & Destructor Documentation

~RefCountingObject()

virtual rwsf::RefCountingObject::~RefCountingObject ( void )

virtual

Destructor.

RefCountingObject() [1/2]

rwsf::RefCountingObject::RefCountingObject ( )

protected

Constructs a default instance (initializes the reference count to 0). Throws no exceptions.

RefCountingObject() [2/2]

rwsf::RefCountingObject::RefCountingObject ( const RefCountingObject & second )

protected

Constructs a copy of second. The reference count is not copied, and is instead initialized to 0.

Member Function Documentation

addRef()

void rwsf::RefCountingObject::addRef

(

void

)

const

Increments the reference count. A call to releaseRef() should be made for each call to addRef(), otherwise a memory leak may occur. This method should only be used with objects allocated on the heap.

operator=()

RefCountingObject & rwsf::RefCountingObject::operator= ( const RefCountingObject & second )

protected

Defines an assignment operator so derived classes can do assignments. This method does not assign the reference count. The existing reference count on the class is used.

releaseRef()

virtual void rwsf::RefCountingObject::releaseRef ( void ) const

virtual

Decrements the reference count. If the reference count reaches 0, this object is deleted. This method should only be used with objects allocated on the heap. This method should not be called before calling addRef(), and should be called once for each call to addRef().
