Class GroupPrincipal

java.lang.Object

org.apache.wiki.auth.GroupPrincipal

All Implemented Interfaces:

java.io.Serializable, java.security.Principal

public final class GroupPrincipal
extends java.lang.Object
implements java.security.Principal, java.io.Serializable

Immutable Principal that represents a Group. GroupPrincipals are injected into a Subject's principal list at the time of authentication (login), and serve as proxies for Group objects for the purposes of making Java 2 security policy decisions. We add GroupPrincipals instead of the actual Groups because calling classes should never be able to obtain a mutable object (Group memberships can be changed by callers). Administrators who wish to grant privileges to specific wiki groups via the security policy file should always specify principals of type GroupPrincipal.

2.3.79
