| SessionMappingCachePolicy | | public SessionMappingCachePolicy(CachePolicy cachePolicy)(Code) | | Constructs a SessionMappingCachePolicy instance which acts as a proxy
of the supplied CachePolicy instance.
Parameters:
cachePolicy - the cache policy to be proxyed |
| attachSessionToUser | | public void attachSessionToUser(Principal session, Principal user)(Code) | | Used to associate a Session Principal with a SSOUser Principal.
This method is invoked by the JBossCatalinaRealm on successful
authentication against the SecurityManager.
Everytime an entry is requested given a user Principal key, before
calling the proxyed CachePolicy, it will map such key to the
session key used for storing cache entries.
Parameters:
session -
Parameters:
user - |
| create | | public void create() throws Exception(Code) | | create the service, do expensive operations etc
|
| destroy | | public void destroy()(Code) | | destroy the service, tear down
|
| flush | | public void flush()(Code) | | Flushes the cached objects from the cache.
All user-to-session mapping are removed as well.
|
| get | | public Object get(Object key)(Code) | | Returns the object paired with the specified key if it's
present in the cache, otherwise must return null.
If the supplied key is a user session principal, it will be
mapped to the associated user.
Parameters:
key - the key paired with the object
See Also: SessionMappingCachePolicy.peek |
| insert | | public void insert(Object key, Object object)(Code) | | Inserts the specified object into the cache following the
implemented policy.
Parameters:
key - the key paired with the object
Parameters:
object - the object to cache

| peek | | public Object peek(Object key)(Code) | | Returns the object paired with the specified key if it's
present in the cache, otherwise must return null.
If the supplied key is a user session principal, it will be

Parameters:
key - the key paired with the object

| remove | | public void remove(Object key)(Code) | | Remove the cached object paired with the specified key.
In case the supplied key is a user principal mapped to a session principal, it will
be removed.
Parameters:
key - the key paired with the object
See Also: SessionMappingCachePolicy.insert |
| size | | public int size()(Code) | | Get the size of the cache.
|
