protected void	addMethods(Iterator<? extends MethodOrMethodContext> methods)
boolean	contains(MethodOrMethodContext m)	Returns true iff method is reachable.
QueueReader<MethodOrMethodContext>	listener()	Returns a QueueReader object containing all methods found reachable so far, and which will be informed of any new methods that are later found to be reachable.
QueueReader<MethodOrMethodContext>	newListener()	Returns a QueueReader object which will contain ONLY NEW methods which will be found to be reachable, but not those that have already been found to be reachable.
int	size()	Returns the number of methods that are reachable.
void	update()	Causes the QueueReader objects to be filled up with any methods that have become reachable since the last call.
