InMemorySessionManager

public InMemorySessionManager(Channel componentChannel,
 String path)

Creates a new session manager with the given channel and path.

The manager handles all requests that match the given path, using the same rules as browsers do for selecting the cookies that are to be sent. The request handler’s priority is set to 1000.

Parameters:

componentChannel - the component channel

path - the path

InMemorySessionManager

public InMemorySessionManager(Channel componentChannel,
 String pattern,
 int priority,
 String path)

Creates a new session manager using the given channel and path.

The manager handles only requests that match the given pattern. The Request handler is registered with the given priority.

This constructor can be used if special handling of top level requests is needed.

Parameters:

componentChannel - the component channel

pattern - the path part of a ResourcePattern

priority - the priority

Method Details

startDiscarding

protected Optional<Instant> startDiscarding(long absoluteTimeout,
 long idleTimeout)

Description copied from class: SessionManager

Start discarding all sessions (generate DiscardSession events) that have reached their absolute or idle timeout.

Do not make the sessions unavailable yet.

Returns the time when the next timeout occurs. This method is called only if at least one of the timeouts has been specified.

Implementations have to take care that sessions are only discarded once. As they must remain available while the DiscardSession event is handled this may require marking them as being discarded.

Specified by:

startDiscarding in class SessionManager

Parameters:

absoluteTimeout - the absolute timeout

idleTimeout - the idle timeout

Returns:

the next timeout (empty if no sessions left)

createSession

Creates a new session with the given id.

Specified by:

createSession in class SessionManager

Parameters:

sessionId -

Returns:

the session

lookupSession

protected Optional<Session> lookupSession(String sessionId)

Description copied from class: SessionManager

Lookup the session with the given id.

Lookup will fail if the session has timed out.

Specified by:

lookupSession in class SessionManager

Parameters:

sessionId -

Returns:

the session

removeSession

protected void removeSession(String sessionId)

Description copied from class: SessionManager

Removes the given session from the cache.

Specified by:
