template<typename T>
virtual bool WPropertyVariable< T >::PropertyConstraint::accept ( boost::shared_ptr< WPropertyVariable< T > >  property,
const T &  value 
) [pure virtual]

This method decides whether the specified value is valid for a specific property.

Parameters:
valuethe new value.
propertythe property to which the value should be set.
Returns:
true whenever the new value is acceptable for the property.

Implemented in WPropertyConstraintMax< T >, WPropertyConstraintMin< T >, WPropertyConstraintIsValid< T >, WPropertyConstraintNotEmpty< T >, WPropertyConstraintIsDirectory< T >, WPropertyConstraintPathExists< T >, and WPropertyConstraintSelectOnlyOne< T >.

template<typename T>
virtual boost::shared_ptr< PropertyConstraint > WPropertyVariable< T >::PropertyConstraint::clone ( ) [pure virtual]
template<typename T>
static boost::shared_ptr< PropertyConstraint > WPropertyVariable< T >::PropertyConstraint::create ( PROPERTYCONSTRAINT_TYPE  type) [static]

This method creates a constraint using the specified type.

This is a useful convenience class for easily adding constraints.

Parameters:
typethe type of the constraint to create
Returns:
NULL if the type is unknown or an constraint instance
