Class AccessControlEntry

java.lang.Object

atg.security.AccessControlEntry

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.security.acl.AclEntry

public class AccessControlEntry
extends java.lang.Object
implements java.io.Serializable, java.security.acl.AclEntry, java.lang.Cloneable

An immutable object that defines a set of access rights granted to a given persona.

java.security.acl.AclEntry compatibility notes:

• Modification is always denied (i.e. addPermission(), removePermission(), setNegativePermissions(), and setPrincipal() will never succeed).
• checkPermission() can only succeed if Permission is an instance of AccessRight.
