-/** Bayeux Interface.<br/>\r
- * This interface represents the server side API for the Bayeux messaging protocol.\r
- * Bayeux is a simple subscribe/publish/receive methodology, not far from JMS, but much simplified.<br/>\r
- * It is used both by the actual implementation and by server side clients.<br/>\r
- * Server side clients use this to create, retrieve and subscribe to channels.\r
- * Server side clients are represented, just like remote clients, through the Client interface.\r
- * <br/>\r
- * The Bayeux implementations is intended to be thread safe and multiple threads may simultaneously call Bayeux methods.\r
- * <br/>\r
- * The Bayeux object, is the starting point for any cometd application relying on the Bayeux object.\r
- * Dependent on the container, the Bayeux object will be stored in the <code>javax.servlet.ServletContext</code> object\r
- * as an attribute under the name <code>Bayeux.DOJOX_COMETD_BAYEUX</code><br/>\r
- * To retrieve this object, one would simply call<br/>\r
- * <code>Bayeux bx = (Bayeux)getServletContext().getAttribute(Bayeux.DOJOX_COMETD_BAYEUX);\r
- * <br/><br/>\r
- * The Bayeux protocol is pretty straight forward and includes a bunch of messaging that is not needed to be known to clients,\r
- * both server side and remote clients.\r
- * This object gets initialized by a container dependent servlet, and the servlet then handles all Bayeux communication from the client.\r
- * Remote messsages are delivered to channels, and to server side clients using the <code>Listener</code> interface.<br/>\r
- * <br/>\r
- * A <code>Bayeux session</code> is active as long as the webapp hosting the Bayeux object is active.<br/>\r
- * When the webapplication shuts down, the Bayeux object will unsubscribe all clients and remove all the active channels.\r

+/** Bayeux Interface.<br/>\r
+ * This interface represents the server side API for the Bayeux messaging protocol.\r
+ * Bayeux is a simple subscribe/publish/receive methodology, not far from JMS, but much simplified.<br/>\r
+ * It is used both by the actual implementation and by server side clients.<br/>\r
+ * Server side clients use this to create, retrieve and subscribe to channels.\r
+ * Server side clients are represented, just like remote clients, through the Client interface.\r
+ * <br/>\r
+ * The Bayeux implementations is intended to be thread safe and multiple threads may simultaneously call Bayeux methods.\r
+ * <br/>\r
+ * The Bayeux object, is the starting point for any cometd application relying on the Bayeux object.\r
+ * Dependent on the container, the Bayeux object will be stored in the <code>javax.servlet.ServletContext</code> object\r
+ * as an attribute under the name <code>Bayeux.DOJOX_COMETD_BAYEUX</code><br/>\r
+ * To retrieve this object, one would simply call<br/>\r
+ * <code>Bayeux bx = (Bayeux)getServletContext().getAttribute(Bayeux.DOJOX_COMETD_BAYEUX);\r
+ * <br/><br/>\r
+ * The Bayeux protocol is pretty straight forward and includes a bunch of messaging that is not needed to be known to clients,\r
+ * both server side and remote clients.\r
+ * This object gets initialized by a container dependent servlet, and the servlet then handles all Bayeux communication from the client.\r
+ * Remote messsages are delivered to channels, and to server side clients using the <code>Listener</code> interface.<br/>\r
+ * <br/>\r
+ * A <code>Bayeux session</code> is active as long as the webapp hosting the Bayeux object is active.<br/>\r
+ * When the webapplication shuts down, the Bayeux object will unsubscribe all clients and remove all the active channels.\r
