Class ContractBuilder

java.lang.Object

edu.uiowa.cs.clc.kind2.lustre.ContractBuilder

public class ContractBuilder
extends java.lang.Object

This class provides helper functions for constructing a contract node. A contract node is very similar to a traditional Lustre node. The two differences are that

• it starts with contract instead of node and
• its body can only mention contract items.

To use a contract node one needs to import it through an inline contract.
