Constructor.

Method Detail

createSession

public Session createSession()

If the session is already created, it is returned. Otherwise the session is created.

Specified by:

createSession in interface SessionManager

Specified by:

createSession in class AbstractSessionManager

Returns:

the one session that is managed by this session manager

See Also:

SessionManager.createSession(), AbstractSessionManager

disposeSession

public void disposeSession(SessionId sessionId)
                    throws DisposeException

Description copied from interface: SessionManager

Disposes a session.

The implementation should call Session.dispose().

The call to this method is irrevokable. If you want to allow for user interaction or server calls before the session or its dialogs are disposed, you should do so before calling.

Note: The implementation must not return before the session is disposed. Any threads or asynchronous calls started must be completed before this method returns.

Specified by:

disposeSession in interface SessionManager

Specified by:

disposeSession in class AbstractSessionManager

Throws:

DisposeException

See Also:

SessionManager.disposeSession(com.sdm.quasar.client.core.application.SessionId)

isStopApplicationAfterLastSession

public boolean isStopApplicationAfterLastSession()

Returns true iff the application will be disposed after the last session has been disposed.

Returns:

true iff the application will be disposed after the last session has been disposed.

setStopApplicationAfterLastSession

public void setStopApplicationAfterLastSession(boolean stopApplicationAfterLastSession)

Sets whether the application will be disposed after the last session has been disposed.

Parameters:

stopApplicationAfterLastSession - if true, the application will be disposed after the last session has been disposed.

collectSystemInfo

public void collectSystemInfo(SystemInfoNode root,
                              SystemInfoOptions options)

Description copied from interface: SystemInfoProvider

Builds the system information tree upon local information of the implementor. The system information tree can be used within development by inspecting the system; so implementors should append their internal state (depending on the details settings within SystemInfoOptions). The information can be appended to the tree by adding new child SystemInformationNodes to the root node given using the SystemInfoNode.createChild(String) method and by setting information attributes the these nodes or the given root node.

Specified by:

collectSystemInfo in interface SystemInfoProvider

Parameters:

root - the SystemInfoNode to add information to (guaranteed to be not null)

options - contains additional options, that might influence the amount of information added to the tree (guaranteed to be not null)
