Detailed Description

template <int I_location, typename T_functor>
struct sigc::hide_functor< I_location, T_functor >

Adaptor that adds a dummy parameter to the wrapped functor.

Use the convenience function sigc::hide() to create an instance of sigc::hide_functor.

The following template arguments are used:

I_location Zero-based position of the dummy parameter (-1 for the last parameter).
T_functor Type of the functor to wrap.

Constructor & Destructor Documentation

template <int I_location, typename T_functor >

sigc::hide_functor< I_location, T_functor >::hide_functor ( const T_functor & func )

inlineexplicit

Constructs a hide_functor object that adds a dummy parameter to the passed functor.

Parameters

func	Functor to invoke from operator()().

template <int I_location, typename T_functor >

template <typename... T_arg>

decltype(auto) sigc::hide_functor< I_location, T_functor >::operator() ( T_arg &&... a )

inline

Invokes the wrapped functor, ignoring the argument at index I_location (0-indexed).

Parameters

a	Arguments to be passed on to the functor, apart from the ignored argument.
