Interface Sid

All Superinterfaces:

Serializable

All Known Implementing Classes:

GrantedAuthoritySid, PrincipalSid

public interface Sid
extends Serializable

A security identity recognised by the ACL system.

This interface provides indirection between actual security objects (eg principals, roles, groups etc) and what is stored inside an Acl. This is because an Acl will not store an entire security object, but only an abstraction of it. This interface therefore provides a simple way to compare these abstracted security identities with other security identities and actual security objects.
