public class LoggingThreadFactory
extends java.lang.Object
implements java.util.concurrent.ThreadFactory, java.lang.Thread.UncaughtExceptionHandler

This thread factory just adds a Thread.UncaughtExceptionHandler to threads it creates so that there are logs of the exceptions that cause threads to die.

Constructor Detail

LoggingThreadFactory

public LoggingThreadFactory(java.lang.String poolName,
                            boolean daemon)

Creates a factory that will produce either daemon or non-daemon threads. Be careful if you pass in false for the daemon parameter; if you do, make sure your thread pool and all its threads created by this factory are properly shutdown; otherwise you could prevent the VM from exiting properly.

Parameters:

poolName - the name of the thread pool that will be using this factory

daemon - if true, the factory will create daemon threads; false for non-daemon threads
