Constructor Detail

LoggingThreadFactory

public LoggingThreadFactory(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
