Class IdentityScope

Implemented Interfaces:
Principal, Serializable
public abstract class IdentityScope
extends Identity
IdentityScope represents a scope of an identity. IdentityScope is also an Identity and can have a name and scope along with the other qualitites identities possess.

An IdentityScope contains other Identity objects. All Identity objects are manipulated in the scope the same way. The scope is supposed to apply different scope to different type of Identities.

No identity within the same scope can have the same public key.
