-/**
- * Wrapper for another HandlerInterface that will only handle a percentage of
- * records offered to it.
- *
- * When HandlerInterface::handle() is called for a given record, it will be
- * handled or ignored with a one in N chance based on the sample factor given
- * for the handler.
- *
- * Usage with MWLoggerMonologSpi:
- * @code
- * $wgMWLoggerDefaultSpi = array(
- *   'class' => 'MWLoggerMonologSpi',
- *   'args' => array( array(
- *     'handlers' => array(
- *       'some-handler' => array( ... ),
- *       'sampled-some-handler' => array(
- *         'class' => 'MWLoggerMonologSamplingHandler',
- *         'args' => array(
- *           function() {
- *             return MWLoggerFactory::getProvider()->getHandler( 'some-handler');
- *           },
- *           2, // emit logs with a 1:2 chance
- *         ),
- *       ),
- *     ),
- *   ) ),
- * );
- * @endcode
- *
- * A sampled event stream can be useful for logging high frequency events in
- * a production environment where you only need an idea of what is happening
- * and are not concerned with capturing every occurence. Since the decision to
- * handle or not handle a particular event is determined randomly, the
- * resulting sampled log is not guaranteed to contain 1/N of the events that
- * occurred in the application but based on [[Law of large numbers]] it will
- * tend to be close to this ratio with a large number of attempts.
