public interface Sid extends Serializable
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.
