Adaptors

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

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.
 
 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()().
 
 track_obj()
 sigc::track_obj() tracks trackable objects, referenced from a functor.
 

Classes

struct  sigc::adaptor_base
 A hint to the compiler. More...
 
struct  sigc::adaptor_functor< T_functor >
 Converts an arbitrary functor into an adaptor type. More...
 
struct  sigc::adaptor_trait< T_functor, I_isadaptor >
 Trait that specifies what is the adaptor version of a functor type. More...
 
struct  sigc::adapts< T_functor >
 Base type for adaptors. More...
 
struct  sigc::deduce_result_type< T_functor, T_args >
 Deduce the return type of a functor. More...
 

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(), track_obj() and group().

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