Class ThreadFilter

java.lang.Object
  de.intarsys.tools.logging.ThreadFilter

All Implemented Interfaces:

Filter

public class ThreadFilter
extends Object
implements Filter

Only accept log requests within a dedicated thread.

This is for example suitable in a scenario where a log should be associated with a functor object but the functor is executed in different worker threads. If the functor activates its filter upon entry, all activities can be sent to the same log, even from different workers. In this case the thread associated with the filter is switched with "activate" and "deactivate". These methods should always be used in a "finally" style block.

Another scenario is where a thread has a dedicated task and all its activities have to be logged. Here the thread is associated at startup and remains the same.
