getDocumentIdsToLock

public List<String> getDocumentIdsToLock(DocumentLockingEvent lockingEvent)
                                  throws Exception

Description copied from interface: PostProcessor

Executed prior to document locking in the workflow engine. This method returns a List 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 list of document ids to lock.

Specified by:

getDocumentIdsToLock in interface PostProcessor

Returns:

a List of document ids to lock prior to execution of the workflow engine

Throws:

Exception
