Method Detail

init

public static void init()

Ensure that Role constants are initialized. Actually does nothing, but the classloader ensures that all static initializers have been run before executing any code in this class. This ensures that Roles required for the Pizza app are created properly before a application code calls Role.get(Constants.Role.XXX)

All Roles have a converse - PizzaProvider/PizzaConsumer for example. The following Role.create calls specify both the Role and its converse. In the case of the Carnivore Role - the Role and its converse are the same. The call to create PizzaProvider, however, designates PizzaConsumer as the converse. (See RelationshipType.PROVIDER definition above.

If Role.get(XXX) is called before a proper Role.create, the Role code will create a default pairing of XXX and ConverseOfXXX Roles. The ConverseOfXXX Role is typically unusable.
