template <class T_return, class T_obj, class T_arg1>
sigc::mem_functor1< T_return, T_obj, T_arg1 >::mem_functor1 ( )
inline

Constructs an invalid functor.

◆ mem_functor1() [2/2]

template <class T_return, class T_obj, class T_arg1>
sigc::mem_functor1< T_return, T_obj, T_arg1 >::mem_functor1 ( function_type _A_func)
inlineexplicit

Constructs a mem_functor1 object that wraps the passed method.

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

◆ operator()() [1/2]

template <class T_return, class T_obj, class T_arg1>
T_return sigc::mem_functor1< T_return, T_obj, T_arg1 >::operator() ( T_obj & _A_obj,
type_trait_take_t< T_arg1 > _A_a1 ) const
inline

Execute the wrapped method operating on the passed instance.

Parameters
_A_objReference to instance the method should operate on.
_A_a1Argument to be passed on to the method.
Returns
The return value of the method invocation.

◆ operator()() [2/2]

template <class T_return, class T_obj, class T_arg1>
T_return sigc::mem_functor1< T_return, T_obj, T_arg1 >::operator() ( T_obj * _A_obj,
type_trait_take_t< T_arg1 > _A_a1 ) 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.
_A_a1Argument to be passed on to the method.
Returns
The return value of the method invocation.
