ConstMethod< R, ClassT, As > Class Template Reference

#include <Pt/ConstMethod.h>

Adapter for const class methods. More...

Inherits Callable< R, As... >.

Public Types
typedef R(ClassT::*	MemFuncT) (As...) const
	The wrapped member function type.

Public Member Functions
	ConstMethod (ClassT &object, MemFuncT method)
	Wraps the given member function of the given object.
ClassT &	object ()
	Returns a reference to this object's bound ClassT object.
const ClassT &	object () const
	Returns a const reference to this object's bound ClassT object.
R	call (As... args) const
	Calls the callable entity and returns its result. More...
void	invoke (As... args) const
	Invokes the invokable entity with the given arguments. More...
bool	operator== (const ConstMethod &other) const
	Returns true if both use the same object and function pointer.
virtual Callable *	clone () const=0
	Returns a copy of this instance. More...
R	operator() (As... args) const
	Same as call().

Related Functions
ConstMethod< R, ClassT, As... >	callable (ClassT &object, R(BaseT::*method)(As...) const)
	Returns a ConstMethod object for the given object/method pair.
Function< R, As... >	callable (R(*function)(As...))
	Returns a Function wrapper for the given free/static function.
Method< R, ClassT, As... >	callable (ClassT &object, R(BaseT::*method)(As...))
	Returns a Method object for the given object/method pair.

Detailed Description

template<typename R, typename ClassT, typename... As>
class Pt::ConstMethod< R, ClassT, As >

The ConstMethod class wraps const member functions as Callable objects so that they can be used with the signals/slots framework.

Member Function Documentation

call()

R call ( As...  args ) const

virtual

This is the primary non-virtual entry point used by Delegate and other callers that need the return value. All derived classes must implement this.

Implements Callable< R, As... >.

invoke()

void invoke ( As...  args ) const

virtual

The passed arguments must match the template parameters.

Implements Callable< R, As... >.

clone()

virtual Callable* clone

pure virtualinherited

A copy of the instance is created with new is returned. Ownership is transfered to the caller, who has to delete it.
