<div class="block">A base class for implementing transport using a polling strategy. The
underlying sockets will be checked in an active loop and woke up when an
socket needed to be processed. This class handle the logic behind binding,
accepting and disposing the server sockets. An <code>Executor</code> will be used
for running client accepting and an <a href="../../../../../org/apache/mina/core/polling/AbstractPollingIoProcessor.html" title="class in org.apache.mina.core.polling"><code>AbstractPollingIoProcessor</code></a> will
be used for processing client I/O operations like reading, writing and
