public class DummyInterpreter
extends Component

This dummy class mimics an interpreter. It reads features and all three kinds of states, and writes all three kinds of states. Real interpreters are likely to only read some of these inputs and only produce some of these outputs. This dummy interpreter illustrates the API using the following aspects:

Method Detail

act

public void act()
         throws javax.jms.JMSException
Description copied from class: Component
Proactive actions. This method is called every Component.waitingTime milliseconds if no messages arrive, and after every message processing. This base implementation does nothing; subclasses should implement suitable behaviour here.

Overrides:
act in class Component
Throws:
javax.jms.JMSException - if communication with the JMS server goes wrong.

react

public void react(SEMAINEMessage m)
           throws javax.jms.JMSException
Description copied from class: Component
Reactions to messages. This base implementation does nothing; subclasses should implement suitable behaviour here.

Overrides:
react in class Component
Throws:
javax.jms.JMSException - if communication with the JMS server goes wrong.
