The GUI manager handles client-specific GUI-issues, for instance, providing a suitable GUI context for applications. This allows for a consistent client-UI by integrating applications into a standard client application user interface, for instance, the Eclipse Rich Client Platform.

Method Detail

getGUIContext

GUIContext getGUIContext(SessionToken session,
                         ActivityInstance activityInstance,
                         EBPInstanceReference ebpInstanceReference,
                         String sessionId,
                         ExecutionContext executionContext,
                         ExecutionControlManager executionControlManager,
                         Thread thread)
                  throws GUIContextUnavailableException

Gets an appropriate GUI context for the designated activity as configured locally for the corresponding client. This method looks for a specific context for the execution environment of the activity. If none is defined, the context for the type of the activity (for instance, a standard GUI for all web services) will be returned. If there is also no definition, a standard GUI context will be returned.
Applications using the GUI context should cast the returned instance to the appropriate implementation.

Parameters:

session - The session which is used to check for access rights on this method.

activityInstance - The activity instance for which a GUI context is to be retrieved. If a localisation is available, it will already be applied.

ebpInstanceReference - The EBP-instance reference (identifies the corresponding instance node) for which a GUI context is to be retrieved.

sessionId - The ID of the session in which the GUI context is needed.

executionContext - The context in which the component the GUI context is retrieved for is executed.

executionControlManager - A reference to control the execution, for instance, to close the application when the user closes the GUI window of the returned GUI context.

thread - The thread, the component runs inside. The GUI context must check calls to it against this thread, to ensure thread safety.

Returns:

The context containing the appropriate GUI for displaying the user interface of an application.

Throws:

GUIContextUnavailableException - If the requested GUI context can not be created, a GUIContextUnavailableException will be thrown.
