<p><a class="link" href="TrackerMiner.html" title="TrackerMiner"><span class="type">TrackerMiner</span></a> is an abstract base class to help developing data miners
for tracker-store, being an abstract class it doesn't do much by itself,

controlled properly by external means such as <a href="../libtracker-control/TrackerMinerManager.html"><span class="type">TrackerMinerManager</span></a>.</p>

give the number expected of seconds to finish processing, 0 if the
value cannot be estimated, and -1 if its not applicable.</p>
