+
+// Only expose a single object name in the global namespace.
+// Everything must go through this module. Global Paho.MQTT module
+// only has a single public function, client, which returns
+// a Paho.MQTT client object given connection details.
+
+/**
+ * Send and receive messages using web browsers.
+ *
+ * This programming interface lets a JavaScript client application use the MQTT V3.1 or
+ * V3.1.1 protocol to connect to an MQTT-supporting messaging server.
+ *
+ * The function supported includes:
+ *
+ * - Connecting to and disconnecting from a server. The server is identified by its host name and port number.
+ *
- Specifying options that relate to the communications link with the server,
+ * for example the frequency of keep-alive heartbeats, and whether SSL/TLS is required.
+ *
- Subscribing to and receiving messages from MQTT Topics.
+ *
- Publishing messages to MQTT Topics.
+ *
+ *
+ * The API consists of two main objects:
+ *
+ * - {@link Paho.MQTT.Client}
+ * - This contains methods that provide the functionality of the API,
+ * including provision of callbacks that notify the application when a message
+ * arrives from or is delivered to the messaging server,
+ * or when the status of its connection to the messaging server changes.
+ * - {@link Paho.MQTT.Message}
+ * - This encapsulates the payload of the message along with various attributes
+ * associated with its delivery, in particular the destination to which it has
+ * been (or is about to be) sent.
+ *
+ *
+ * The programming interface validates parameters passed to it, and will throw
+ * an Error containing an error message intended for developer use, if it detects
+ * an error with any parameter.
+ *
+ * Example:
+ *
+ *
+client = new Paho.MQTT.Client(location.hostname, Number(location.port), "clientId");
+client.onConnectionLost = onConnectionLost;
+client.onMessageArrived = onMessageArrived;
+client.connect({onSuccess:onConnect});
+function onConnect() {
+ // Once a connection has been made, make a subscription and send a message.
+ console.log("onConnect");
+ client.subscribe("/World");
+ message = new Paho.MQTT.Message("Hello");
+ message.destinationName = "/World";
+ client.send(message);
+};
+function onConnectionLost(responseObject) {
+ if (responseObject.errorCode !== 0)
+ console.log("onConnectionLost:"+responseObject.errorMessage);
+};
+function onMessageArrived(message) {
+ console.log("onMessageArrived:"+message.payloadString);
+ client.disconnect();
+};
+ *
+ * Most applications will create just one Client object and then call its connect() method,
+ * however applications can create more than one Client object if they wish.
+ * In this case the combination of host, port and clientId attributes must be different for each Client object.
+ *
+ * The send, subscribe and unsubscribe methods are implemented as asynchronous JavaScript methods
+ * (even though the underlying protocol exchange might be synchronous in nature).
+ * This means they signal their completion by calling back to the application,
+ * via Success or Failure callback functions provided by the application on the method in question.
+ * Such callbacks are called at most once per method invocation and do not persist beyond the lifetime
+ * of the script that made the invocation.
+ *
+ * In contrast there are some callback functions, most notably onMessageArrived,
+ * that are defined on the {@link Paho.MQTT.Client} object.
+ * These may get called multiple times, and aren't directly related to specific method invocations made by the client.
+ *
+ * @name Paho.MQTT.Client
+ *
+ * @constructor
+ *
+ * @param {string} host - the address of the messaging server, as a fully qualified WebSocket URI, as a DNS name or dotted decimal IP address.
+ * @param {number} port - the port number to connect to - only required if host is not a URI
+ * @param {string} path - the path on the host to connect to - only used if host is not a URI. Default: '/mqtt'.
+ * @param {string} clientId - the Messaging client identifier, between 1 and 23 characters in length.
+ *
+ * @property {string} host - read only the server's DNS hostname or dotted decimal IP address.
+ * @property {number} port - read only the server's port.
+ * @property {string} path - read only the server's path.
+ * @property {string} clientId - read only used when connecting to the server.
+ * @property {function} onConnectionLost - called when a connection has been lost.
+ * after a connect() method has succeeded.
+ * Establish the call back used when a connection has been lost. The connection may be
+ * lost because the client initiates a disconnect or because the server or network
+ * cause the client to be disconnected. The disconnect call back may be called without
+ * the connectionComplete call back being invoked if, for example the client fails to
+ * connect.
+ * A single response object parameter is passed to the onConnectionLost callback containing the following fields:
+ *
+ * - errorCode
+ *
- errorMessage
+ *
+ * @property {function} onMessageDelivered - called when a message has been delivered.
+ * All processing that this Client will ever do has been completed. So, for example,
+ * in the case of a Qos=2 message sent by this client, the PubComp flow has been received from the server
+ * and the message has been removed from persistent storage before this callback is invoked.
+ * Parameters passed to the onMessageDelivered callback are:
+ *
+ * - {@link Paho.MQTT.Message} that was delivered.
+ *
+ * @property {function} onMessageArrived - called when a message has arrived in this Paho.MQTT.client.
+ * Parameters passed to the onMessageArrived callback are:
+ *
+ * - {@link Paho.MQTT.Message} that has arrived.
+ *
+ * @property {function} onConnected - called when a connection is successfully made to the server.
+ * after a connect() method.
+ * Parameters passed to the onConnected callback are:
+ *
+ * - reconnect (boolean) - If true, the connection was the result of a reconnect.
+ * - URI (string) - The URI used to connect to the server.
+ *
+ * @property {boolean} disconnectedPublishing - if set, will enable disconnected publishing in
+ * in the event that the connection to the server is lost.
+ * @property {number} disconnectedBufferSize - Used to set the maximum number of messages that the disconnected
+ * buffer will hold before rejecting new messages. Default size: 5000 messages
+ * @property {function} trace - called whenever trace is called. TODO
