移除书签- Starting execution before an activity
- Starting execution after an activity on its single outgoing sequence flow
- Starting execution on a specific sequence flow
- Cancelling an activity instance, transition instance, or all instances (activity or transition) for an activity
Instructions are executed asynchronous and in the order they are provided in this request's body. Variables can be provided with every starting instruction.
The exact semantics of modification can be read about in the user guide.
Method
POST
Parameters
A JSON object with the following properties:
|type|Mandatory. One of the following values:
cancel, startBeforeActivity, startAfterActivity, startTransition. A instruction requests cancellation of a single activity instance or all instances of one activity. A startBeforeActivity instruction requests to enter a given activity. A startAfterActivity instruction requests to execute the single outgoing sequence flow of a given activity. A startTransition instruction requests to execute a specific sequence flow.|activityId|Can be used with instructions of types startBeforeActivity, startAfterActivity, and cancel. Specifies the activity the instruction targets.|transitionId|Can be used with instructions of types startTransition. Specifies the sequence flow to start.|activityInstanceId|Can be used with instructions of type cancel. Specifies the activity instance to cancel. Valid values are the activity instance IDs supplied by the request.|transitionInstanceId|Can be used with instructions of type cancel. Specifies the transition instance to cancel. Valid values are the transition instance IDs supplied by the Get Activity Instance request.|ancestorActivityInstanceId|Can be used with instructions of type
startBeforeActivity, startAfterActivity, and startTransition. Valid values are the activity instance IDs supplied by the request.
If there are multiple parent activity instances of the targeted activity, this specifies the ancestor scope in which hierarchy the activity/transition is to be instantiated.
Example: When there are two instances of a subprocess and an activity contained in the subprocess is to be started, this parameter allows to specify under which subprocess instance the activity should be started.
|type|Mandatory. One of the following values: cancel, startBeforeActivity, startAfterActivity, startTransition. A cancel instruction requests cancellation of a single activity instance or all instances of one activity. A startBeforeActivity instruction requests to enter a given activity. A startAfterActivity instruction requests to execute the single outgoing sequence flow of a given activity. A startTransition instruction requests to execute a specific sequence flow.
|activityId|Can be used with instructions of types startBeforeActivity, , and cancel. Specifies the activity the instruction targets.
|transitionId|Can be used with instructions of types startTransition. Specifies the sequence flow to start.
|activityInstanceId|Can be used with instructions of type cancel. Specifies the activity instance to cancel. Valid values are the activity instance IDs supplied by the Get Activity Instance request.
|transitionInstanceId|Can be used with instructions of type cancel. Specifies the transition instance to cancel. Valid values are the transition instance IDs supplied by the request.
|ancestorActivityInstanceId|
Can be used with instructions of type startBeforeActivity, startAfterActivity, and startTransition. Valid values are the activity instance IDs supplied by the Get Activity Instance request.
Example: When there are two instances of a subprocess and an activity contained in the subprocess is to be started, this parameter allows to specify under which subprocess instance the activity should be started.
