Diagram Editor

Overview

Actifsource offers graphical editors to view and edit the meta-model and model. For editing the model it is possible to define domain-specific editors.

Class Diagram Editor

The class diagram editor allows you to create new meta-models based on Actifsource classes.

New Class Diagram

You can create a new class diagram via context menu in the project explorer or File/New.

Preselecting a package will directly fill in the resource path and package in the wizard.

Palette

Use the palette to edit your diagram.

Select Selects one or many classes from the diagram. Use Ctrl+Click for multi select.
Marquee Selects classes from the diagram within a rectangle.
Extension Derives a class from another class by adding a Class.extend statement in the sub class.

Inserting an extends-relation from MySubClass to MyClass would add an extends-relation from MySubClass to MyClass as expected. At the same time the extends-relation from MySubSubClass to NamedResource is removed because MyClass already extends NamedResource.
The same rule also applies when extending from Resource.

Info

Note that are special rules for your convenience. Consider creating two new Classes MyClass and MySubClass Both are extending NamedResource by default.

Relation Inserts a relation from a class to another. Select one of the relation types or a base relation. Selecting a base relation automatically selects the relation type needed (see Chapter Property).

Note Connects class to any note. See also New Note.
New Class Inserts a new class on the diagram and in the model. Note that the preselected namespace (package and/or containing resource) is the same as the package of the class diagram.

Info

Note that you can directly select the super class in this dialog. While NamedResource is the default you may select**Resource** to create an unnamed resource, or any other Class. For other properties see also Chapter 4.6.1 ch.actifsource.core.Class.

New Enum Inserts a new enum on the diagram and in the model. For other properties see also Chapter 4.6.2 ch.actifsource.core.Enum.
New Note Inserts a new note on the diagram. Click on the first text line of the note to enter the edit mode.

Drag and Drop

Use the drag and drop feature from the project explorer to add an existing class to your diagram.

Use the context menu on the diagram background.

Show Shows any existing resource in the scope of your project. Use this feature to insert resources from third party or Actifsource models to your diagram (i.e. Actifsource Core Model).

Use the content menu on any class.

Delete from Diagram Deletes this class from the diagram only but not from the model. Use Delete on the keyboard to delete selected classes from the diagram.
Delete from Model Deletes this class from the diagram and from the model. Use Shift+Delete on the keyboard to delete selected classes from the diagram and from the model.
Show Attributes Shows attributes (literals) in an UML-like style.

Hide Attributes Hides shown attribute (see also Show Attributes).
Instances Inserts instances of a specific class on the diagram.
Types Shows the types (Class.typeOf statement) of a specific class.
Super Class Shows the superclass (Class.extend statement) of a specific class. You this feature repeatedly to show the inheritance hierarchy.

Browse Resource

Open any class in the resource editor by Ctrl+Click on the class name.

Domain Diagram Editor

The domain diagram editor allows you to create new models based on your meta-model.

New Domain Diagram

You can create a new class diagram via context menu in the project explorer or File/New.

Preselecting a package will directly fill in the resource path and package in the wizard.

Name The name of the domain diagram.
Diagram Type Every domain uses its own diagram styles. The DiagramType lets you define your domain-specific domain diagrams (see Chapter 6 Domain Diagram Type).
If there is no diagram type defined, the diagram editor has a default behavior and shows resources and their relationships (use and own relation, dependencies).

As a very simple example, let us define a diagram type for a state machine meta-model.

As the root class (see also Single Root) we choose Statemachine. This means that we can only edit elements that are part of the state machine.

The allowed class is State since we like to edit states. Between states there are transitions. A Transition is an indirect relation from State via Transition to State.

The minimal diagram type shown above leads to a domain specific state event diagram.

SingleRoot If there is a single root defined, every resource is created in the context of the single root. If no single root is defined, resources are created in the same package as the domain diagram.

Info

Note that defining a rootClass in the DiagramType demands for a singleRoot in the domain diagram.

New Domain Diagram for Resource

You can create a new domain diagram for a single root directly by calling New/Domain Diagram on a resource.

Info

Note that the single root is preselected in the wizard and the diagram type is automatically detected if there is a diagram type which has a root class of the same type as the chosen single root.
