corresponding java.util.logging.Logger instance. LogKit from Apache's Avalon project. Each named Log instance is connected to a corresponding LogKit Logger. NoOpLog implementation that simply swallows all log output, for all named Log isntances. SimpleLog implementation that writes all log output, for all named Log instances, to System.err. Quick Start Guide For those impatient to just get on with it, the following example illustrates the typical declaration and use of a logger that is named (by convention)...

<p class="rule">
A successful call to <code>l.TryLock</code> (or <code>l.TryRLock</code>)

An unsuccessful call has no synchronizing effect at all.
