Contexts

A diagram in the diagram tool is always the context of a certain class or cluster. Context means the direct relations up to a certain depth.

For clusters, the relations are:

• subclusters
• superclusters

The relations for classes are:

• ancestors
• descendants
• clients
• suppliers

This is an example of the class LIST, with ancestor depth 2, descendant depth 2 and both client and supplier depth zero.
