Public Member Functions inherited from lout::object::Object
virtual	~Object ()
	The destructor is defined as virtual (but not abstract), so that destruction of Object's works properly.

virtual bool	equals (Object *other)
	Returns, whether two objects are equal.

virtual int	hashValue ()
	Return a hash value for the object.

virtual Object *	clone ()
	Return an exact copy of the object.

char *	toString ()
	Use object::Object::intoStringBuffer to return a textual representation of the object.

virtual size_t	sizeOf ()
	Return the number of bytes, this object totally uses.

A sub class must implement this for a call to a single receiver.

This methods gets the signal in a folded representation, it has to unfold it, and pass it to a single receiver. For boolean signals, the return value of the receiver must be returned, for void signals, the return value is discarded.

Implements lout::signal::Emitter.
