public DelegationPermission(String name,
                    String actions)

Parameters:

name - the name

actions - the actions; this is ignored

Method Detail

implies

public boolean implies(Permission perm)

Description copied from class: BasicPermission

This method tests to see if the specified permission is implied by this permission. This will be true if the following conditions are met:

• The specified object is an instance of the same class as this object.
• The name of the specified permission is implied by this permission's name based on wildcard matching. For example, "a.*" implies "a.b".

Overrides:

implies in class BasicPermission

Parameters:

perm - the Permission object to test against

Returns:

true if the specified permission is implied

newPermissionCollection

public PermissionCollection newPermissionCollection()

Description copied from class: BasicPermission

This method returns an instance of PermissionCollection suitable for storing BasicPermission objects. The collection returned can only store objects of the same type as this. Subclasses which use actions must override this method; but a class with no actions will work fine with this.

Overrides:

newPermissionCollection in class BasicPermission

Returns:

a new empty PermissionCollection object
