Detailed Description

template<class T_return, class T_obj>

class sigc::const_mem_functor0< T_return, T_obj >

const_mem_functor0 wraps const methods with 0 argument(s).

Use the convenience function mem_fun() to create an instance of const_mem_functor0.

The following template arguments are used:

  • T_return The return type of operator()().
  • T_obj The object type.

Constructor & Destructor Documentation

template <class T_return , class T_obj >
sigc::const_mem_functor0< T_return, T_obj >::const_mem_functor0 ( )
inline

Constructs an invalid functor.

template <class T_return , class T_obj >
sigc::const_mem_functor0< T_return, T_obj >::const_mem_functor0 ( function_type  _A_func)
inlineexplicit

Constructs a const_mem_functor0 object that wraps the passed method.

Parameters
_A_funcPointer to method will be invoked from operator()().

Member Function Documentation

template <class T_return , class T_obj >
T_return sigc::const_mem_functor0< T_return, T_obj >::operator() ( const T_obj *  _A_obj) const
inline

Execute the wrapped method operating on the passed instance.

Deprecated:
Please use the constructor that takes the object by reference instead.
Parameters
_A_objPointer to instance the method should operate on.
Returns
The return value of the method invocation.
template <class T_return , class T_obj >
T_return sigc::const_mem_functor0< T_return, T_obj >::operator() ( const T_obj &  _A_obj) const
inline

Execute the wrapped method operating on the passed instance.

Parameters
_A_objReference to instance the method should operate on.
Returns
The return value of the method invocation.
