Detailed Description

template <class T_return, class T_obj>
class sigc::mem_functor0< T_return, T_obj >

mem_functor0 wraps methods with 0 argument(s).

Use the convenience function mem_fun() to create an instance of mem_functor0.

The following template arguments are used:

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

mem_functor0() [1/2]

template <class T_return , class T_obj >

sigc::mem_functor0< T_return, T_obj >::mem_functor0 ( )

inline

Constructs an invalid functor.

mem_functor0() [2/2]

template <class T_return , class T_obj >

sigc::mem_functor0< T_return, T_obj >::mem_functor0 ( function_type  _A_func )

inlineexplicit

Constructs a mem_functor0 object that wraps the passed method.

Parameters

Member Function Documentation

operator()() [1/2]

template <class T_return , class T_obj >

T_return sigc::mem_functor0< T_return, T_obj >::operator() ( T_obj &  _A_obj ) const

inline

Execute the wrapped method operating on the passed instance.

Parameters

_A_obj

Reference to instance the method should operate on.

Returns

The return value of the method invocation.

operator()() [2/2]

template <class T_return , class T_obj >

T_return sigc::mem_functor0< T_return, T_obj >::operator() ( 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_obj

Pointer to instance the method should operate on.

Returns

The return value of the method invocation.
