Public Member Functions | |
Referenced () | |
Referenced (const Referenced &) | |
Referenced & | operator= (const Referenced &) |
void | ref () const |
increment the reference count by one, indicating that this object has another pointer which is referencing it. | |
void | unref () const |
decrement the reference count by one, indicating that a pointer to this object is referencing it. | |
void | unref_nodelete () const |
decrement the reference count by one, indicating that a pointer to this object is referencing it. | |
int | referenceCount () const |
return the number pointers currently referencing this object. | |
Static Public Member Functions | |
static void | setThreadSafeReferenceCounting (bool enableThreadSafeReferenceCounting) |
Set whether reference counting should be use a mutex to create thread reference counting. | |
static bool | getThreadSafeReferenceCounting () |
Get whether reference counting is active. | |
static void | setDeleteHandler (DeleteHandler *handler) |
Set a DeleteHandler to which deletion of all referenced counted objects will be delegated to. | |
static DeleteHandler * | getDeleteHandler () |
Get a DeleteHandler. | |

|
Get a DeleteHandler.
|
|
Get whether reference counting is active.
|
|
|
|
increment the reference count by one, indicating that this object has another pointer which is referencing it.
|
|
return the number pointers currently referencing this object.
|
|
Set a DeleteHandler to which deletion of all referenced counted objects will be delegated to.
|
|
Set whether reference counting should be use a mutex to create thread reference counting.
|
|
decrement the reference count by one, indicating that a pointer to this object is referencing it. If the reference count goes to zero, it is assumed that this object is no longer referenced and is automatically deleted. |
|
decrement the reference count by one, indicating that a pointer to this object is referencing it. However, do not delete it, even if ref count goes to 0. Warning, unref_nodelete() should only be called if the user knows exactly who will be resonsible for, one should prefer unref() over unref_nodelete() as the later can lead to memory leaks. |
