+ * Event listener adapter that delegates the handling of messages to target
+ * listener methods via reflection, with flexible event type conversion.
+ * Allows listener methods to operate on event content types, completely
+ * independent from the GemFire API.
+ * 
+ * <p/>Modeled as much as possible after the JMS MessageListenerAdapter in
+ * Spring Framework.
+ *
+ * <p>By default, the content of incoming GemFire events gets extracted before
+ * being passed into the target listener method, to let the target method
+ * operate on event content types such as Object or Operation instead of
+ * the raw {@link CqEvent}.
+ *
+ * <p>Find below some examples of method signatures compliant with this
+ * adapter class. This first example handles all <code>CqEvent</code> types
+ * and gets passed the contents of each <code>event</code> type as an
+ * argument.
+ *
+ * <pre class="code">public interface PojoListener {
+ *    void handleMessage(CqEvent event);
