IdentityScope (Java SE 21 & JDK 21)

All Implemented Interfaces:

Serializable, Principal

This class represents a scope for identities. It is an Identity itself, and therefore has a name and can have a scope. It can also optionally have a public key and associated certificates.

An IdentityScope can contain Identity objects of all kinds, including signers. All types of Identity objects can be retrieved, added, and removed using the same methods. Note that it is possible, and in fact expected, that different types of identity scopes will apply different policies for their various operations on the various types of Identities.

There is a one-to-one mapping between keys and identities, and there can only be one copy of one key per scope. For example, suppose Acme Software, Inc is a software publisher known to a user. Suppose it is an Identity, that is, it has a public key, and a set of associated certificates. It is named in the scope using the name "Acme Software". No other named Identity in the scope has the same public key. Of course, none has the same name as well.

    First, if there is a security manager, its checkSecurityAccess method is called with "setSystemScope" as its argument to see if it's ok to set the identity scope.

    Parameters:

    scope - the scope to set.

    Throws:

    SecurityException - if a security manager exists and its checkSecurityAccess method doesn't allow setting the identity scope.
