Modules
	bind(), bind_return()
	sigc::bind() alters an arbitrary functor by fixing arguments to certain values.
	compose()
	sigc::compose() combines two or three arbitrary functors.
	exception_catch()
	sigc::exception_catch() catches an exception thrown from within the wrapped functor and directs it to a catcher functor.
	group()
	sigc::group() alters an arbitrary functor by rebuilding its arguments from one or more lambda expressions.
	hide(), hide_return()
	sigc::hide() alters an arbitrary functor in that it adds a parameter whose value is ignored on invocation of the returned functor.
	retype(), retype_return()
	sigc::retype() alters a sigc::pointer_functor, a sigc::mem_functor or a sigc::slot in that it makes C-style casts to the functor's parameter types of all parameters passed through operator()().

Detailed Description

Adaptors are functors that alter the signature of a functor's operator()().

The adaptor types libsigc++ provides are created with bind(), bind_return(), hide(), hide_return(), retype_return(), retype(), compose(), exception_catch() and group().

You can easily derive your own adaptor type from sigc::adapts.

Function Documentation

template <class T_action , class T_functor >

void sigc::visit_each	(	const T_action &	_A_action,
		const adaptor_functor< T_functor > &	_A_target
	)

Performs a functor on each of the targets of a functor.

The function overload for sigc::adaptor_functor performs a functor on the functor stored in the sigc::adaptor_functor object.
