Class MethodInvokerThread

java.lang.Object

java.lang.Thread

org.fcrepo.server.utilities.MethodInvokerThread

All Implemented Interfaces:

Runnable

public class MethodInvokerThread
extends Thread

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.
