## Detailed Description

### template <class T_return, class T_obj, class T_arg1>
class sigc::bound_const_mem_functor1< T_return, T_obj, T_arg1 >

bound_const_mem_functor1 encapsulates a const method with 1 arguments and an object instance.

Use the convenience function mem_fun() to create an instance of bound_const_mem_functor1.

The following template arguments are used:

- T_arg1 Argument type used in the definition of operator()().
- T_return The return type of operator()().
- T_obj The object type.

## Constructor & Destructor Documentation

template <class T_return , class T_obj , class T_arg1 >

sigc::bound_const_mem_functor1< T_return, T_obj, T_arg1 >::bound_const_mem_functor1 | ( | const T_obj * | _A_obj,
|  | function_type | _A_func |
| ) |  |  | `[inline]`

Constructs a bound_const_mem_functor1 object that wraps the passed method.

Parameters:

  | _A_obj | Pointer to instance the method will operate on.
  | _A_func | Pointer to method will be invoked from operator()().

template <class T_return , class T_obj , class T_arg1 >

sigc::bound_const_mem_functor1< T_return, T_obj, T_arg1 >::bound_const_mem_functor1 | ( | const T_obj & | _A_obj,
|  | function_type | _A_func |
| ) |  |  | `[inline]`

Constructs a bound_const_mem_functor1 object that wraps the passed method.

Parameters:

  | _A_obj | Reference to instance the method will operate on.
  | _A_func | Pointer to method will be invoked from operator()().

## Member Function Documentation

template <class T_return , class T_obj , class T_arg1 >

T_return sigc::bound_const_mem_functor1< T_return, T_obj, T_arg1 >::operator() | ( | typename type_trait< T_arg1 >::take | _A_a1 | ) | const`[inline]`

Execute the wrapped method operating on the stored instance.

Parameters:

  | _A_a1 | Argument to be passed on to the method.

Returns:
  The return value of the method invocation.
