public class Right
extends Object

A Right instance encapsulates a SecurableObject, a RightType and optional constraints which restrict it's applicability.

For example, one instance of a RightSet may be the 'access'-Right to a geographic dataset restricted to a certain area and weekdays. The situation (requested area and current time) is coded as a Feature object.

Constructor Summary

Right(SecurableObject object, RightType type)
Creates a new Right -instance (with no constraints).

Right(SecurableObject object, RightType type, Filter constraints)
Creates a new Right -instance.

Method Summary

boolean	applies(SecurableObject object) Checks if the Right applies on the given SecurableObject and in unrestricted manner (w/o constraints).
boolean	applies(SecurableObject object, Feature situation) Checks if the Right applies on the given SecurableObject and in a concrete situation (the situation is represented by the given Feature).
Filter	getConstraints() Returns the restrictions (the parameters) of this Right.
SecurableObject	getSecurableObject() Returns the associated SecurableObject.
RightType	getType() Returns the associated RightType.
Right	merge(Right that) Generates the disjunctive combination of the instance and the submitted Right, so that the new Right has the permissions of both instances.
String	toString() Returns a String representation of this object.
