Description copied from interface: IWorkflowEventHandler

Check if this event handler may handle the given event.

This method should return false if this event handler's state is inactive.

Note: despite this method returns true the event handler is not required to return its efferent transition when process is being called.

Parameters:

p_evt - The event.

p_wfCtx - The workflow processing context.

Returns:

true if this event handler may process this event, or false otherwise.

process

public WorkflowTransition process(IWorkflowEvent p_evt,
                                  de.uplanet.lucy.server.workflow.IWorkflowProcessingContext p_wfCtx,
                                  de.uplanet.lucy.server.IProcessingContext p_ctx)

Description copied from interface: IWorkflowEventHandler

Process a workflow event in the given context.

This method is called by the workflow engine if a call to isHandlerFor returned true. However this method is not required to return a non-null efferent transition in such cases.

A workflow event handler must return null if it is not active.

Parameters:

p_evt - The event to be processed.

p_wfCtx - The workflow processing context.

p_ctx - The processing context.

Returns:

The efferent transition, or null.
