Class RightSet

java.lang.Object
  extended by org.deegree.security.drm.model.RightSet

public class RightSet
extends java.lang.Object

A RightSet encapsulates a number of Right objects. This are grouped by the SecurableObject for which they apply to support an efficient implementation of the merge()-operation. The merge()-operation results in a RightSet that contains the logical rights of boths sets, but only one Right object of each RightType (and SecurableObject). This is accomplished by merging the constraints of the Rights of the same type (and object).

                       Feature situation)
                throws GeneralSecurityException
Checks if the RightSet contains the permissions for a SecurableObject and a concrete situation (the situation is represented by the given Feature).

Parameters:
object -
type -
situation -
Returns:
true, if the right applies
Throws:
GeneralSecurityException

applies

public boolean applies(SecurableObject object,
                       RightType type)
Checks if the RightSet contains the (unrestricted) permissions for a SecurableObject and a certain type of right.

Parameters:
object -
type -

                      RightType type)
Parameters:
secObject -
type -
Returns:
the Right of the specified RightType that this RightSet defines on the specified SecurableObject.

toArray

public Right[] toArray(SecurableObject secObject)
Parameters:
secObject -
Returns:
the encapulated Rights (for one SecurableObject) as an one-dimensional array.

toArray2

public Right[][] toArray2()
Returns:
the encapulated Rights as a two-dimensional array:
