Interface AuthenticationCache

All Known Implementing Classes:

NoAuthenticationCache, SimpleExpiryCache

public interface AuthenticationCache

Interface for a cached of the authentication information.

Implementations should provide a public constructor with one argument of type Properties. The property object passed at construction contains the same properties that were passed to flexible JDBC realm. This allows users of a cache to configure a cache through the standard Glassfish security realm configuration.

Implementations should implemnet #toString() to print a meaningful description of the cache for logging.

This interface is very similar to the AuthenticationRepository but is slightly different because it gets cached data and does not 'find' it. Also the contract differs in that it may return null and it has method for putting things into it.
