Class BasicSessionUserTable

java.lang.Object
  com.lutris.appserver.server.session.BasicSessionUserTable

All Implemented Interfaces:: StandardSessionUserTable

Direct Known Subclasses:: PagedSessionUserTable

class BasicSessionUserTable
extends java.lang.Object
implements StandardSessionUserTable

Table used by StandardSessionManager to cross reference User objects and sessions. This table does not hold references to the user and session objects. Instead it only cross-references the session keys and user names. An underlying assumption is that the user name can be used as a unique reference to the user. N.B. It is assumed that this class is only used by StandardSessionManager and that it is responsible for providing high level locks instead of synchronizing
