IdentityAsserter (Java API Reference for Oracle WebLogic Server)

```
public interface IdentityAsserter
```
The IdentityAsserter interface exposes the methods that custom Identity Assertion providers need to implement in order to provide token-based client identity assertion. An Identity Assertion provider is a specific form of Authentication provider that is used to establish a client's identity outside of the request.

javax.security.auth.callback.CallbackHandler assertIdentity(java.lang.String type,
                                                            java.lang.Object token)
                                                     throws IdentityAssertionException
```
    Asserts an identity based on token identity information. An instance of the Identity Assertion provider's CallbackHandler will be passed to the LoginModules to perform principal mapping. A null CallbackHandler instance signifies that the anonymous user should be used.
    This method is called every time identity assertion occurs, but the LoginModules may not be called if the Subject is cached. The -Dweblogic.security.identityAssertionTTL flag can be used to affect this behavior (for example, to modify the default TTL of 5 minutes or to disable the cache by setting the flag to -1).
    It is the responsibility of the Identity Assertion provider to ensure not just that the token is valid, but also that the user is still valid (for example, the user has not been deleted).
    
    Parameters:
    
    type - the type of token to use for identity assertion
    
    token - the actual token to be used to assert identity
    
    Returns:
    
    a CallbackHandler related to the identity, or null to signify the anonymous user
    
    Throws:
    
    IdentityAssertionException - if the identity assertion fails.
