public class RealmPermission

extends Permission

A RealmPermission class is defined to represent permissions for a realm. It extends from java.security.Permission, thus can be used just like any regular Java permission.

A RealmPermission consists of the name of the realm (also known as permission target name) and a set of "actions" specifying privileges applicable to that realm. The target name of a RealmPermission instance is the name of the realm in question.

The individual action name is specific to the realm in question and are system-defined.

The following table lists all the system-defined RealmPermission action names:


Permission Action	the Permission Action Allows
createRealm	Create realms
dropRealm	Drop realms
createUser	Create users in the target realm.
dropUser	Drop users in the target realm.
createRole	Create roles in the target realm.
dropRole	Drop roles in the target realm.
modifyRole	Modify roles in the target realm.
grantRole	Grant roles in the target realm.
revokeRole	Revoke roles from the target realm
