Class ContractId<T>

  • Type Parameters:
    T - A template type
    All Implemented Interfaces:
    Exercises<ExerciseCommand>
    public class ContractId<T>
extends java.lang.Object
implements Exercises<ExerciseCommand>
    This class is used as a super class for all concrete ContractIds generated by the java codegen with the following properties: 
     Foo.ContractId fooCid = new Foo.ContractId("test");
 Bar.ContractId barCid = new Bar.ContractId("test");
 ContractId<Foo> genericFooCid = new ContractId<>("test");
 ContractId<Foo> genericBarCid = new ContractId<>("test");

 fooCid.equals(genericFooCid) == true;
 genericFooCid.equals(fooCid) == true;

 fooCid.equals(barCid) == false;
 barCid.equals(fooCid) == false;
    Due to erase, we cannot distinguish ContractId<Foo> from ContractId<Bar>, thus: 
     fooCid.equals(genericBarCid) == true
 genericBarCid.equals(fooCid) == true

 genericFooCid.equals(genericBarCid) == true
 genericBarCid.equals(genericFooCid) == true
