All Implemented Interfaces:

Runnable

public class SubTxThread
extends Thread

A thread class for subtransaction threads. A SubTxThread is a thread whose code is automatically executed in a subtransaction of the calling thread's transaction. Creation, start and end of the subtransaction is done by the system so the programmer does not have to worry about that. To create a new instance, you need a Waiter and a SubTxCode instance.
