All Implemented Interfaces:

java.lang.Runnable

public class MethodInvokerThread

extends java.lang.Thread

Title: MethodInvokerThread.java

Description: A Thread that invokes a single method, then exits.

This is convenient in situations where some method should run in a separate Thread, but it is either inconvenient or inappropriate to write a Runnable to do the work.
