Modeling Activities

By adding class operations, you can model the behavior of the classes from the data model. For class operations, you can select from different types of implementation:

An activity diagram is a graphical representation of a workflow. Step-by-step, you can define the actions to be performed. By using decisions, local variables, and more, you can implement complex behavior.

Creating an Activity Operation

To create an activity operation, use the quick action Create a new activity operation of a class:

Enter a name for the operation and click Save:

Restrictions on Element Names

A process name must be unique within one service. In addition, the following name restrictions apply to all service panel elements:

Element names...

  • ... must not be empty.

  • ... must not contain spaces. Exception: Spaces are allowed in operation names.

  • ... must not start with numbers.

  • ... must not contain a dot ( . ).

  • ... must not contain any special characters. Exception: Operation names may end with a slash ( / ).

  • In addition, Action Script commands and some system-relevant strings (refer to Reserved Words) cannot be used as element names.

Your input is validated: If the name you enter violates these restrictions, the field in the editor turns red and cannot be saved.

Alternatively, you can open the context menu of the class and select Create > Operation:

The dialog Create Operation opens. Select Activity from the drop-down list of available implementation types, enter a name for the operation and click Save to create the operation:

The new operation is added to the class. It opens automatically in a new Designer tab, and you can directly start modeling your activity:

Refer to Working with the Activity Editor for detailed information.

Once the operation has been created, you can use the quick actions and the context menu to manage it:

You can:

  • add parameters

    • in

    • out

    • return

  • add suboperations

  • open the implementation of the activity diagram

  • cut the operation

  • copy the operation

  • paste the operation (available if Copy or Cut option have been used before)

  • rename the operation

  • delete the operation

Refer to Implementation and Modeling Data Structures for more information on your options and how to create classes and operations.

Overview on the Activity Diagram Editor

When you create a class operation that is implemented by an activity diagram, the activity diagram editor opens:

Use the various functionalities of the activity diagram editor to model your activity:

Name

Description

(1)

Activity Editor

The activity editor is where you model your activity diagram.
Refer to Working with the Activity Editor for detailed information about the features of the activity diagram editor.

(2)

Elements Toolbar

The elements toolbar contains all UML elements that you can create on the diagram pane.
Refer to Working with the Activity Editor for further details about the usage of the toolbar.
Refer to Supported UML Elements in the PAS Designer Developer Guide for details about all UML elements.

(3)

Model Toolbar

The model toolbar assists you during modeling on the diagram pane.
Refer to Working with the Activity Editor for an overview of the available options of the model toolbar.

(4)

Designer Panels

In the activity diagram editor, the following panels assist you during modeling:

  • Service Panel: In the service panel you can manage the contents of your whole service such as you BPMN and data model, forms and used libraries.
    Refer to Service Panel and Working With Libraries for detailed information.

  • Attributes Panel: Use the attributes panel to change the settings of the activity diagram elements and the diagram pane.
    Refer to Changing the Attributes of Elements on the Activity Diagram for detailed information.

  • Validation Panel: The validation panel supports you during modelling by displaying notes for invalid actions in your models or forms. It also gives advice on how to fix the errors.
    Refer to Validating a Service for detailed information.

The following panel is hidden by default. If you use the panel preset, you can find the icon to open this panel in the right upper corner of the diagram panel:

  • Overview Panel: In the overview panel, your model and a blue frame are displayed, representing the content shown on the diagram pane. Use the panel to keep the overview of your BPMN model - and to navigate within.
    Refer to Working with the Activity Editor for further information about the Overview panel.

Attributes of an Activity Operation

Select an activity operation in the Implementation folder of the service panel to display its attributes in the Attributes panel. You can also edit them there:

Activity operations have the following attributes:

Attribute

Description

Possible Values / Example

Name

Click here to change the Name of the related operation.

Activity operation names must follow certain naming rules. They

  • must not contain blanks

  • must not start with a number

  • must not contain special characters

checkSupportManager

Description

If you want to insert or change a description for the respective activity operation, click here to open a text editor where you can enter and format your text.


Is static

Specify if the operation is static (default) or not.

  • Static activity operations can be called without creating an instance of the related class. They get all necessary data via their input parameters.

  • Wanting to call a non-static activity operation, you need to create a local instance of the related class, and call the operation on that object. This is called self Context.

For more information, also refer to Adding Operation Calls.

true

The activity operation is static (default) and can be used outside the context of the related class.

false

The activity operation is non-static and needs a self object as an input.

Extensions

By clicking Add, you can add extensions to an activity operation.
By adding an extension, you can add additional attributes to an activity operation.
