Detailed Description

This is an object shared by all the weak pointers that point to the same ReferenceCount object.

It is created whenever a weak reference to an object is created, and can outlive the object until all weak references have disappeared.

Constructor & Destructor Documentation

◆ ~WeakReferenceList()

WeakReferenceList::~WeakReferenceList ( )

The destructor tells all of the owned references that we're gone.

Definition at line 29 of file weakReferenceList.cxx.

Member Function Documentation

◆ add_callback()

void WeakReferenceList::add_callback	(	WeakPointerCallback *	callback,
		void *	data
	)

Adds the callback to the list of callbacks that will be called when the underlying pointer is deleted.

If it has already been deleted, it will be called immediately.

The data pointer can be an arbitrary pointer and is passed as only argument to the callback.

Since: 1.10.0

Definition at line 44 of file weakReferenceList.cxx.

Referenced by WeakPointerToVoid::add_callback().

◆ ref()

void WeakReferenceList::ref ( ) const

inline

Increases the number of weak references.

Since: 1.10.0

Definition at line 20 of file weakReferenceList.I.

◆ remove_callback()

void WeakReferenceList::remove_callback ( WeakPointerCallback * callback )

Intended to be called only by WeakPointerTo (or by any class implementing a weak reference-counting pointer), this removes the indicated PointerToVoid structure from the list of such structures that are maintaining a weak pointer to this object.
