A graphic component encapsulates a model, a view, and a controller.
The equipment component, like all the other graphic components, is
based on the MVC architecture, which means that it has a model, a
view and a controller associated with it. For a general
introduction to the MVC architecture, see Architecture of graphic components.
The MVC architecture for the equipment
component is implemented by the following classes:
- The class IlpEquipment contains a model, a view, and a controller.
- The model interfaces are IlpEquipmentModel and IlpMutableEquipmentModel. IlpMutableEquipmentModel provides API facilities for adding and removing objects. The two equipment model interfaces are implemented through the class IlpDefaultEquipmentModel. Instances of IlpEquipment use the class IlpDefaultEquipmentModel.The representation objects to be displayed in the equipment component must be added to the model. The equipment model recognizes the following objects: nodes, and links that connect nodes. The representation objects to be added to the model must implement the IlpEquipmentNode or IlpEquipmentLink interface. Concrete implementations of these interfaces are provided as IlpDefaultEquipmentNode and IlpDefaultEquipmentLink. You can create subclasses of these representation object classes.
- The class IlpEquipmentView defines the equipment view that is automatically instantiated when an equipment object (an instance of
IlpEquipment) is created. - The class IlpEquipmentController creates a controller that manages interactions between the user and an IlpEquipmentView.
