1.1.5 Decomposition structure

Depending on the method in use, an object (e.g. a State in a WatchApplication) can be decomposed into a new graph (Figure 1–5). This feature is usually known as decomposition or leveling as it forms a hierarchy of models.

Figure 1–5. Decomposition structure.

Note that only zero or one decomposition is allowed for an object, and applies in all graphs containing that object. A graph can however be the target of a decomposition of multiple objects. Decomposition links are normally between graphs of the same type.
