Class NullStatelessTicketCache

java.lang.Object
  org.springframework.security.providers.cas.cache.NullStatelessTicketCache

All Implemented Interfaces:

StatelessTicketCache

public final class NullStatelessTicketCache
extends Object
implements StatelessTicketCache

Implementation of @link StatelessTicketCache that has no backing cache. Useful in instances where storing of tickets for stateless session management is not required.

This is the default StatelessTicketCache of the @link CasAuthenticationProvider to eliminate the unnecessary dependency on EhCache that applications have even if they are not using the stateless session management.
