Defining Relations

You may want to refer to section Relations for an overview of relations in Server.

This section demonstrates how to define relations between the classes that make up a server object model.

You will define the following relations:

• A network that owns one or more domains.

To define such a relation, you will use the server class template IlsOwnsList which lets you declare a one-to-many ownership relation.

• A domain that owns one or more nodes and also one or more lines.

To define such a relation, you will also use the server class template IlsOwnsList.

• A line that uses an input node and an output node.

To define such a relation, you will use the server class template . which lets you declare a one-to-one use relation.

These class templates take two arguments:

• the name of the class that will be the origin of the relation, and

• the class that will be the target of the relation.
