DelegationPermission

public DelegationPermission(String name,
                            String actions)
Create a new instance with the given name and actions. The name consists of two parts: first the subordinate service principal, then the target service principal. Each principal is surrounded by quotes; the two are separated by a space.
Parameters:
name - the name
actions - the actions; this is ignored

Method Details

implies

public boolean implies(Permission perm)
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 interface BasicPermission
Parameters:
perm - the Permission object to test against
Returns:
true if the specified permission is implied

newPermissionCollection

public PermissionCollection newPermissionCollection()
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 interface BasicPermission
Returns:
a new empty PermissionCollection object
