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.

Right

public Right(SecurableObject object,
             RightType type)

Creates a new Right -instance (with no constraints).

object -

type -

Right

public Right(SecurableObject object,
             RightType type,
             Filter constraints)

Creates a new Right -instance.

Parameters:

object -

constraints - null means that no constraints are defined

Method Detail

getSecurableObject

public SecurableObject getSecurableObject()

Returns:

the associated SecurableObject.

getType

public RightType getType()

Returns:

the associated RightType.

getConstraints

public Filter getConstraints()

Returns the restrictions (the parameters) of this Right.

Returns:

null, if no constraints are defined

merge

public Right merge(Right that)
            throws GeneralSecurityException

Parameters:

that -

Returns:

the disjunctive combination of the instance and the submitted Right, so that the new Right has the permissions of both instances.

Throws:

GeneralSecurityException

applies

public boolean applies(SecurableObject object,
                       Feature situation)
                throws GeneralSecurityException

Parameters:

object -

situation -

Returns:

true if the Right applies on the given SecurableObject and in a concrete situation (the situation is represented by the given Feature).

Throws:

GeneralSecurityException

applies

public boolean applies(SecurableObject object)

Parameters:

object -

Returns:

true if the Right applies on the given SecurableObject and in unrestricted manner (w/o constraints).

toString

public String toString()

Overrides:

toString in class Object
