A Basic Graphics Application Model

To use ILOG JViews effectively, you need to understand how to use ILOG JViews Framework, and to use the Framework, you need to understand the basic object model, that is, the core Java objects and their relationships to each other.

A basic graphics application needs just a few parts:

graphic objects (manipulated with resize, select, and draw functionality),
a data structure to put them into, and
a viewport (typically a rectangular area in a window on the display) which enables to zoom in and out on the graphic objects that are drawn in it.

In the ILOG JViews world, we formally refer to these parts as IlvGraphic, IlvManager, and IlvManagerView objects, respectively. Their organization is shown in Figure 1.1.

Figure 1.2 shows the same classes represented as a UML class diagram.
