  • Method Details

    • getConstrainedClass

      public static ConstrainedClass getConstrainedClass(Class<?> theClass)
      Get the ConstrainedClass for the given class
      Parameters:
      theClass - the class to be wrapped
      Returns:
      the ConstrainedClass that wraps the given class
      Throws:
      IllegalArgumentException - if the provided class is null

    • isConstraint

      public static boolean isConstraint(Annotation annotation)
      Parameters:
      annotation - the annotation to test
      Returns:
      true if the given annotation is a Constraint
      Throws:
      IllegalArgumentException - if the annotation is null

    • getConstraints

      public Set<Annotation> getConstraints(String propertyName) throws IntrospectionException
      Get an immutable set of constraints for a given property. The constraints may be annotated either on the getter or the setter method and may be anywhere within the class hierarchy. The result is a set of constraints that must all be satisfied for the property to be valid.
      Parameters:
      propertyName - name of the property
      Returns:
      the set (immutable) of constraints (annotations) or an empty set if there are no constraints on that property
      Throws:
      IntrospectionException - if there are problems accessing the property
      IllegalArgumentException - if the propertyName is null

    • getConstrainedProperties

      public Set<String> getConstrainedProperties()
      Returns:
      a set of properties that have constraints associated with them
