doRouteStatusChange

public boolean doRouteStatusChange(DocumentRouteStatusChangeDTO statusChangeEvent)
                            throws RemoteException

Description copied from interface: PostProcessorRemote

The document has changed route status. The docEvent contains the information about the change. This method should do what ever is appropriate for various route status changes to a document. The method should return true if the change is correct and all application actions as a result of the change are successful. It should return false if the application considers this an incorrect change. The method can throw a ResourceUnavailableException in order to requeue the document and try again later.

Specified by:

doRouteStatusChange in interface PostProcessorRemote

Returns:

true if the status change is correct and application actions are successful later if this exception is thrown

Throws:

RemoteException

doDeleteRouteHeader

public boolean doDeleteRouteHeader(DeleteEventDTO event)
                            throws RemoteException

Description copied from interface: PostProcessorRemote

KEW is signaling that the document should be deleted. The application can reject this by returning false. If an Exception is thrown the docuemnt will go to exception routing. If a ResourceUnavailableException is thrown, the doc will be requeued and will try again later to delete the document.

Specified by:

doDeleteRouteHeader in interface PostProcessorRemote

Returns:

Throws:

RemoteException

doActionTaken

public boolean doActionTaken(ActionTakenEventDTO event)
                      throws RemoteException

Description copied from interface: PostProcessorRemote

Specified by:

doActionTaken in interface PostProcessorRemote

Returns:

Throws:

RemoteException

beforeProcess

public boolean beforeProcess(BeforeProcessEventDTO event)
                      throws Exception

Description copied from interface: PostProcessorRemote

The document is about to be processed by the Workflow engine.

Specified by:

beforeProcess in interface PostProcessorRemote

Parameters:

event - - holder for data from the engine's process

Returns:

true if the method is successful, false otherwise

Throws:

Exception - A general Exception will put the document into Exception routing

afterProcess

public boolean afterProcess(AfterProcessEventDTO event)
                     throws Exception

Description copied from interface: PostProcessorRemote

The document has just completed processing by the Workflow engine.

Specified by:

afterProcess in interface PostProcessorRemote

Parameters:

event - - holder for data from the engine's process including whether the engine was successful or not

Returns:

true if the method is successful, false otherwise

Throws:

Exception - A general Exception will put the document into Exception routing

getDocumentIdsToLock

public String[] getDocumentIdsToLock(DocumentLockingEventDTO event)
                              throws Exception

Description copied from interface: PostProcessorRemote

Executed prior to document locking in the workflow engine. This method returns an array of document ids to lock prior to execution of the document in the workflow engine. If the engine processing is going to result in updates to any other documents, they should be locked at the beginning of the engine processing transaction. This method facilitates that.

Note that, by default, the id of the document that is being processed by the engine is always locked. So there is no need to return that document id in the array of document ids to lock.

Specified by:

getDocumentIdsToLock in interface PostProcessorRemote

Returns:

an array of document ids to lock prior to execution of the workflow engine

Throws:

Exception
