In UML, the tasks to perform by an activity are implemented to action nodes. In the Designer, you can add actions to the activity diagram by dragging out operations from the service panel and dropping them on the canvas.
Activities are modeled in activity diagrams. Refer to Modeling Activities for more information on how to create an activity diagram.
You can do this with any operation: Operations from your data model or the Base Types, as well as operations from imported libraries or connectors.
Dropping an operation on the activity diagram creates a call operation action and the related pins.
| Once added to the diagram, you can move action nodes any time. Click the action node and drag it to a new position. |
| You can resize action nodes by clicking the square in the bottom right corner of the element and dragging it. |
| You can hover over the action node to see a tooltip showing the full operation name and path. |
| Hovering over an operation pin shows the direction, the name and the full path of the type. |
