public class WFStart
extends Component

There are two ways of using the workflows: in memory or persisted (long running). Long running workflows are stored in a database; the process definition of which it is an instance, must also be stored in the database. So when a long running workflow is created, the name and optional version specifiy with definition to use. The resulting workflow is persisted in the database, so it can be identified through an "id". The id is what is managed by the Cheyenne application (by storing it in a variable and optionally in some database). In-memory workflows are never stored in any kind of database, therefore there also is no list of existing process definitions to create a workflow from; there simply is no database. So in-memory workflows have to be created from the XML each and every time. The XML can me written in-line or in a separate file (for re-use), referenced through a url. When a workflow is created, the actual object must be stored, in this case in the same context as the variable. In order to be compatible with long running workflows, an ID is returned, which denotes the workflow. The id is what is managed by the Cheyenne application (by storing it in a variable), but it is quite useless to store this id in a database.

determineIfLongRunning

public static boolean determineIfLongRunning(String id)

Parameters:

id -

Returns:

determineScopeId

public static String determineScopeId(String id)

Parameters:

id -

Returns:

determineProcessId

public static long determineProcessId(String id)

Parameters:

id -

Returns:

determineTokenId

public static long determineTokenId(String id)

Parameters:

id -

Returns:

runWithCorrectProcessInstance

public static void runWithCorrectProcessInstance(Dialog dialog,
                                                 String id,
                                                 WFStart.RunnableWithCorrectProcessInstance runnable)

Parameters:

id -

runnable -

makeSureTokenHasPrefix

public static String makeSureTokenHasPrefix(String wfid,
                                            long tokenId)

When you have a token from the wf, you need to prefix it. Suppose you have a workflow "LR:3" and you split child tokens 4 and 5, then using "LR:3" you need to return "LR:4" and "LR:5"

Parameters:

wfid -

tokenId -

Returns:
