 <div class="block">An abstract implementation of the BackendListenerClient interface. This
  implementation provides default implementations of most of the methods in the
  interface, as well as some convenience methods, in order to simplify
  development of BackendListenerClient implementations.

  While it may be necessary to make changes to the BackendListenerClient interface
  from time to time (therefore requiring changes to any implementations of this
  interface), we intend to make this abstract class provide reasonable
  implementations of any new methods so that subclasses do not necessarily need
  to be updated for new versions. Therefore, when creating a new
  BackendListenerClient implementation, developers are encouraged to subclass this
  abstract class rather than implementing the BackendListenerClient interface
  directly. Implementing BackendListenerClient directly will continue to be
  supported for cases where extending this class is not possible (for example,
  when the client class is already a subclass of some other class).
  <p>
  The <a href="BackendListenerClient.html#handleSampleResults(java.util.List,org.apache.jmeter.visualizers.backend.BackendListenerContext)"><code>BackendListenerClient.handleSampleResults(java.util.List, BackendListenerContext)</code></a>
  method of BackendListenerClient does not have a default
  implementation here, so subclasses must define at least this method. It may
  be useful to override other methods as well.</div>
