This permission cannot be used for controlling access to resources as the Security Manager is no longer supported.

This class is for Kerberos delegation permissions.

The target name of this Permission specifies a pair of kerberos service principals. The first is the subordinate service principal being entrusted to use the TGT. The second service principal designates the target service the subordinate service principal is to interact with on behalf of the initiating KerberosPrincipal. This latter service principal is specified to restrict the use of a proxiable ticket.

public boolean implies(Permission p)

Overrides java.security.BasicPermission.implies.

Checks if this Kerberos delegation permission object "implies" the specified permission.

This method returns true if this DelegationPermission is equal to p, and returns false otherwise.

Parameters

newPermissionCollectionback to summary
public PermissionCollection newPermissionCollection()

Overrides java.security.BasicPermission.newPermissionCollection.

Returns a PermissionCollection object for storing DelegationPermission objects.
DelegationPermission objects must be stored in a manner that allows them to be inserted into the collection in any order, but that also enables the PermissionCollection implies method to be implemented in an efficient (and consistent) manner.

Returns:PermissionCollection

a new PermissionCollection object suitable for storing DelegationPermissions.
