IdentityScope

public abstract class IdentityScope
extends Identity

java.lang.Object
   ↳ java.security.Identity
     ↳ java.security.IdentityScope


This class was deprecated in API level 1.
This class is no longer used. Its functionality has been replaced by java.security.KeyStore, the java.security.cert package, and java.security.Principal.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.

This constructor is used for serialization only and should not be used by subclasses.

Public methods

addIdentity

Added in API level 1
void addIdentity (Identity identity)

Adds an identity to this identity scope.

Parameters
identity Identity: the identity to be added.
Throws
KeyManagementException if the identity is not valid, a name conflict occurs, another identity has the same public key as the identity being added, or another exception occurs.

getIdentity

Added in API level 1
Identity getIdentity (String name)

Returns the identity in this scope with the specified name (if any).

Parameters
name String: the name of the identity to be retrieved.
Returns
Identity the identity named name, or null if there are no identities named name in this scope.

getIdentity

Added in API level 1
Identity getIdentity (PublicKey key)

Retrieves the identity with the specified public key.

Parameters
key PublicKey: the public key for the identity to be returned.
Returns
Identity the identity with the given key, or null if there are no identities in this scope with that key.

getIdentity

Added in API level 1
Identity getIdentity (Principal principal)

Retrieves the identity whose name is the same as that of the specified principal. (Note: Identity implements Principal.)

Parameters
principal Principal: the principal corresponding to the identity to be retrieved.
Returns
Identity the identity whose name is the same as that of the principal, or null if there are no identities of the same name in this scope.

getSystemScope

Added in API level 1
IdentityScope getSystemScope ()

Returns the system's identity scope.

Returns
IdentityScope the system's identity scope, or null if none has been set.

Returns
Enumeration<Identity> an enumeration of all identities in this identity scope.

removeIdentity

Added in API level 1
void removeIdentity (Identity identity)

Removes an identity from this identity scope.

Parameters
identity Identity: the identity to be removed.
Throws
KeyManagementException if the identity is missing, or another exception occurs.

size

Added in API level 1
int size ()

Returns the number of identities within this identity scope.

Protected methods

setSystemScope

Added in API level 1
void setSystemScope (IdentityScope scope)

Sets the system's identity scope.

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 IdentityScope: the scope to set.
Throws
SecurityException if a security manager exists and its checkSecurityAccess method doesn't allow setting the identity scope.
