Public Functions

virtual void onEvent(IEvent *e) = 0

Function to be implemented that will handle an event.

Parameters

e – The event to process. To stop further propagation of the event, call IEvent::consume().

virtual size_t addRef() = 0

Atomically add one to the reference count.

Returns

The current reference count after one was added, though this value may change before read if other threads are also modifying the reference count. The return value is guaranteed to be non-zero.

virtual size_t release() = 0

Atomically subtracts one from the reference count.

If the result is zero, carb::deleteHandler() is called for this.

Returns

The current reference count after one was subtracted. If zero is returned, carb::deleteHandler() was called for this.
