Detailed Documentation

Wraps a freestanding function or static member function for use as a Delegate.

Methods

virtual
bool
notify(const void* sender)

Invokes the delegate’s callback function.

Returns true if successful, or false if the delegate has been disabled or has expired.

virtual
AbstractDelegate<void>*
clone() const

Returns a deep copy of the AbstractDelegate.

virtual
void
disable()

Disables the delegate, which is done prior to removal.
