PropertyConstraint () | |
Default constructor. | |
virtual | ~PropertyConstraint () |
Destructor. | |
virtual bool | accept (boost::shared_ptr< WPropertyVariable< T > > property, const T &value)=0 |
This method decides whether the specified value is valid for a specific property. | |

Allows simple identification of the real constraint type. | |
virtual boost::shared_ptr < PropertyConstraint > | clone ()=0 |
Method to clone the constraint and create a new one with the correct dynamic type. | |
Static Public Member Functions | |
static boost::shared_ptr < PropertyConstraint > | create (PROPERTYCONSTRAINT_TYPE type) |
This method creates a constraint using the specified type. |

This method decides whether the specified value is valid for a specific property.
value | the new value. |
property | the property to which the value should be set. |
Implemented in WPropertyConstraintMax< T >, WPropertyConstraintMin< T >, WPropertyConstraintIsValid< T >, WPropertyConstraintNotEmpty< T >, WPropertyConstraintIsDirectory< T >, WPropertyConstraintPathExists< T >, and WPropertyConstraintSelectOnlyOne< T >.
virtual boost::shared_ptr< PropertyConstraint > WPropertyVariable< T >::PropertyConstraint::clone | ( | ) | [pure virtual] |
Method to clone the constraint and create a new one with the correct dynamic type.
Implemented in WPropertyConstraintMax< T >, WPropertyConstraintMin< T >, WPropertyConstraintIsValid< T >, WPropertyConstraintNotEmpty< T >, WPropertyConstraintIsDirectory< T >, WPropertyConstraintPathExists< T >, and WPropertyConstraintSelectOnlyOne< 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.
type | the type of the constraint to create |
PROPERTYCONSTRAINT_TYPE WPropertyVariable< T >::PropertyConstraint::getType | ( | ) | [virtual] |
Allows simple identification of the real constraint type.
Reimplemented in WPropertyConstraintMax< T >, WPropertyConstraintMin< T >, WPropertyConstraintIsValid< T >, WPropertyConstraintNotEmpty< T >, WPropertyConstraintIsDirectory< T >, WPropertyConstraintPathExists< T >, and WPropertyConstraintSelectOnlyOne< T >.
