public class LatchedThreadGroup
extends org.apache.avalon.framework.logger.AbstractLogEnabled

This class is useful for writing MultiThreaded test cases where you need to perform multithreaded load testing on a component.

An instance of will create a block of threads of the specified size. Each thread will be assigned to run a specified Runnable instance. The threads will then all wait at a latch until the go method is called. The go method will not return until all of the Runnables have completed.
