Detailed Description

This class allows constraining properties to only be set if a isValid method returns true.

This constraint is especially useful for class-type typenames T providing a isValid method.

Constructor & Destructor Documentation

template<typename T >

WPropertyConstraintIsValid< T >::WPropertyConstraintIsValid ( )

Constructor.

template<typename T >

WPropertyConstraintIsValid< T >::~WPropertyConstraintIsValid ( ) [virtual]

Destructor.

template<typename T >

bool WPropertyConstraintIsValid< T >::accept	(	boost::shared_ptr< WPropertyVariable< T > >	property,
		const T &	value
	)		`[virtual]`

Checks whether the specified new value is a valid, using T::isValid.

Parameters:

property	the property whose new value should be set.
value	the new value to check

template<typename T >

boost::shared_ptr< typename WPropertyVariable< T >::PropertyConstraint > WPropertyConstraintIsValid< T >::clone ( ) [virtual]

Method to clone the constraint and create a new one with the correct dynamic type.

template<typename T >

PROPERTYCONSTRAINT_TYPE WPropertyConstraintIsValid< T >::getType ( ) [virtual]

Allows simple identification of the real constraint type.
