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