org.safs.staf.service.logging.SLSLogFacility.WorkerThread

All Implemented Interfaces:

java.lang.Runnable

Enclosing class:

SLSLogFacility

protected abstract class SLSLogFacility.WorkerThread
extends java.lang.Thread

This is the worker thread that fulfills the log message request received by this log facility. This thread constantly checks the request queue for incoming log message requests and carries them out. It only exits the run method if an EXIT request is found on the queue.

Subclass of SLSLogFacility should derive its worker thread class from this class and implement the log method.
