      gov.sandia.ccaffeine.dc.user_iface.MVC.event.ThreadWaitForResultSet

All Implemented Interfaces:

ResultSetListener, java.lang.Runnable, java.util.EventListener

public class ThreadWaitForResultSet
extends java.lang.Thread
implements ResultSetListener

We sent a query to an entity. Wait for that entity to respond. The entity will either send us the result set or send us an exception.

We have two possible scenarios. In the first scenario, this thread is started BEFORE the entity sends back a result set in response to the query. In the second scenario, this thread is started AFTER the entity sens back a result set.

SCENARIO:
this thread is started
this thread waits for the ResultSetEvent to arrive
entity processes query and sends ResultSetEvent
This thread terminates

SCENARIO:
entity processes query and sends ResultSetEvent
this thread is started
this thread immediately terminates
