~SoCallbackList () | |
void | addCallback (SoCallbackListCB *f, void *userData=NULL) |
void | removeCallback (SoCallbackListCB *f, void *userdata=NULL) |
void | clearCallbacks (void) |
int | getNumCallbacks (void) const |
void | invokeCallbacks (void *callbackdata) |
This list stores callback function pointers (along with user-specified extra data to pass to the callbacks) and provides a method for triggering the callback functions.
|
Default constructor. |
|
Destructor. |
|
Append the callback function f to the list. It will be passed the userdata upon invocation. |
|
Remove callback f from the list. |
|
Remove all callbacks in the list. |
|
Returns number of callback functions. |
|
Invoke all callback functions, passing the userdata and the callbackdata as the first and second argument, respectively. All callbacks registered when the method is invoked will be triggered, even though if the code in one callback removes another callback. It is safe for a callback to remove itself or any other callbacks during execution. |
