## Detailed Description

template <class T_return, class T_obj>
class sigc::const_volatile_mem_functor0< T_return, T_obj >

const_volatile_mem_functor0 wraps const volatile methods with 0 argument(s).

Use the convenience function mem_fun() to create an instance of const_volatile_mem_functor0.

The following template arguments are used:

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

template <class T_return, class T_obj>

sigc::const_volatile_mem_functor0< T_return, T_obj >::const_volatile_mem_functor0 | ( |  | ) |
| inline

Constructs an invalid functor.

## ◆ const_volatile_mem_functor0() [2/2]

template <class T_return, class T_obj>

sigc::const_volatile_mem_functor0< T_return, T_obj >::const_volatile_mem_functor0 | ( | function_type | _A_func | ) |
| inlineexplicit

Constructs a const_volatile_mem_functor0 object that wraps the passed method.

Parameters

  _A_func | Pointer to method will be invoked from operator()().

## Member Function Documentation

## ◆ operator()() [1/2]

template <class T_return, class T_obj>

T_return sigc::const_volatile_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_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::const_volatile_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_obj | Pointer to instance the method should operate on.

Returns
  The return value of the method invocation.
