		const std::string &	signal,
		const Slot &	slot
	)			[pure virtual]

Calls the detached method on the observer, if it derives from Observer.

This method is typically only called by Subject::detach.

Parameters:

	subject	The Subject that the slot is being detached from.
	signal	The name of the signal the Slot is being detached from.
