Differences of Operations
Operations in a library can be static or non-static operations.
| |||
| |||
| |||
You have two options to determine the target of a non-static operation:
|
Adding Operations
Select the operation you want to use from the library panel. Drag & drop the operation to the action operations flow in the execution canvaspane.
| |||||||||||||
When the operation has been added to the action operations flow of the execution UML, the displayed pins indicate needed object flows.
| |||||||||||||
Pins on the left of the action node indicate needed incoming object flow. | |||||||||||||
Pins on the right indicate outgoing object flow. | |||||||||||||
Target pins indicate the target of the operation which is the object element to which the operation is to be applied. | |||||||||||||
Now you need to connect the pins with the corresponding objectsvariables. Depending on which data is required, you can use objects variables from the Persisted or Local section.
| |||||||||||||
| |||||||||||||
You can use the search to narrow down the content of the list. | |||||||||||||
When the persisted object variable is displayed on the canvasexecution pane, draw the necessary object flow to the operation call. | |||||||||||||
While dragging the object flow, the color of the pins assists you:
| |||||||||||||
| Object flows on the execution pane are routed automatically . You can use the execution pane context menu to change the algorithm of the relation path. | ||||||||||||
| You can also Nevertheless you can select an object flow to highlight it in blue - in larger models this helps to track the paths more easily. | ||||||||||||
You can also hover over an object flow to highlight it in black. |
Special Case: Guard Expressions
Guard expressions (conditions) of exclusive gateways are implemented to the outgoing relations of the gateway. If you select the outgoing relation of an exclusive gateway on the BPMN canvasdiagram pane, section Return is displayed in the execution canvas pane automatically. This section contains the unchangeable object return of type Boolean. | |
Operations that should be able to be used on a guard need to have a Boolean return value. This value should transport the following meaning:
Set the return value of the guard expression by connecting the output pin of the operation call to the return object. |
