Method Detail

getServiceInterface

public Class<? extends ServiceInterface> getServiceInterface()

createUserSession

public Session createUserSession(long timeToLiveMs,
                                 long timeToIdleMs,
                                 String defaultGroup)

Description copied from interface: ISession

Allows a user to open up another session for him/herself with the given defaults without needing to re-enter password. TODO Review the security of this method.

Specified by:

createUserSession in interface ISession

createSessionWithTimeout

public Session createSessionWithTimeout(Principal principal,
                                        long milliseconds)

Description copied from interface: ISession

Allows an admin to create a Session for the give Principal

Specified by:

createSessionWithTimeout in interface ISession

Parameters:

principal - Non-null Principal with the target user's name

milliseconds - The time that this Session has until destruction. This is useful to override the server default so that an initial delay before the user is given the token will not be construed as idle time. A value less than 1 will cause the default max timeToLive to be used; but timeToIdle will be disabled.

createSessionWithTimeouts

public Session createSessionWithTimeouts(Principal principal,
                                         long timeToLiveMilliseconds,
                                         long timeToIdleMilliseconds)

Description copied from interface: ISession

Allows an admin to create a Session for the give Principal

Specified by:

createSessionWithTimeouts in interface ISession

Parameters:

principal - Non-null Principal with the target user's name

timeToLiveMilliseconds - The time that this Session has until destruction. Setting the value to 0 will prevent destruction unless the session remains idle.

timeToIdleMilliseconds - The time that this Session can remain idle before being destroyed. Setting the value to 0 will prevent idleness based destruction.

createSession

public Session createSession(Principal principal,
                             String credentials)

Description copied from interface: ISession

Creates a new session and returns it to the user.

Specified by:

createSession in interface ISession

getSession

public Session getSession(String sessionUuid)

Description copied from interface: ISession

Retrieves the session associated with this uuid, updating the last access time as well. Throws a RemovedSessionException if not present, or a SessionTimeoutException if expired. This method can be used as a Session ping.

Specified by:

getSession in interface ISession

getReferenceCount

public int getReferenceCount(String sessionUuid)

Description copied from interface: ISession

Retrieves the current reference count for the given uuid. Has the same semantics as ISession.getSession(String).

Specified by:

getReferenceCount in interface ISession

updateSession

public Session updateSession(Session session)

closeSession

public int closeSession(Session session)

Description copied from interface: ISession

Closes session and releases all resources. It is preferred that all clients call this method as soon as possible to free memory, but it is possible to not call close, and rejoin a session later. The current reference count for the session is returned. If the session does not exist, -1. If this call caused the death of the session, then -2.

Specified by:

closeSession in interface ISession

getMyOpenSessions

public List<Session> getMyOpenSessions()

Description copied from interface: ISession

Returns a list of open sessions for the current user. The list is ordered by session creation time, so that the last item was created last.

Specified by:

getMyOpenAgentSessions

public List<Session> getMyOpenAgentSessions(String agent)

Description copied from interface: ISession

Like ISession.getMyOpenSessions() but returns only those sessions with the given agent string.

Specified by:

getMyOpenClientSessions

public List<Session> getMyOpenClientSessions()

Description copied from interface: ISession

Like ISession.getMyOpenSessions() but returns only those sessions started by official OMERO clients.
