- Method Detail
  - check
```
void check(QValue value)
    throws ConstraintViolationException,
           RepositoryException
```
    Check if the specified value matches this constraint.
    
    Parameters:
    
    value - The value to be tested.
    
    Throws:
    
    ConstraintViolationException - If the specified value is null or does not matches the constraint.
    
    RepositoryException - If another error occurs.
  - getString
```
String getString()
```
    For constraints that are not namespace prefix mapping sensitive this method returns the same defined in PropertyDefinition.getValueConstraints().
    Those that are namespace prefix mapping sensitive (e.g. NameConstraint, PathConstraint and ReferenceConstraint) return an internal string.
    
    Returns:
    
    the internal definition String
