Detailed Documentation

Methods

virtual
bool
notify(
    const void* sender,
    TArgs& arguments
    )

Invokes the delegate’s callback function.

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

virtual
bool
equals(const AbstractDelegate<TArgs>& other) const

Compares the AbstractDelegate with the other one for equality.

virtual
AbstractDelegate<TArgs>*
clone() const

Returns a deep copy of the AbstractDelegate.

virtual
void
disable()

Disables the delegate, which is done prior to removal.
