\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 * The API consists of two main objects:\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 * \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 * All attributes may be null, which implies the default values.\n\t *\n\t * @name Paho.Message\n\t * @constructor\n\t * @param {String|ArrayBuffer} payload The message data to be sent.\n\t * \n\t * @property {string} payloadString read only The payload as a string if the payload consists of valid UTF-8 characters.\n\t * @property {ArrayBuffer} payloadBytes read only The payload as an ArrayBuffer.\n\t * \n\t * @property {string} destinationName mandatory The name of the destination to which the message is to be sent\n\t * (for messages about to be sent) or the name of the destination from which the message has been received.\n\t * (for messages received by the onMessage function).\n\t * \n\t * @property {number} qos The Quality of Service used to deliver the message.\n\t * \n\t * @property {Boolean} retained If true, the message is to be retained by the server and delivered\n\t * to both current and future subscriptions.\n\t * If false the server only delivers the message to current subscribers, this is the default for new Messages.\n\t * A received message has the retained boolean set to true if the message was published\n\t * with the retained boolean set to true\n\t * and the subscrption was made after the message has been published.\n\t * \n\t * @property {Boolean} duplicate read only If true, this message might be a duplicate of one which has already been received.\n\t * This is only set on messages received from the server.\n\t *\n\t */\n\t\tvar Message = function (newPayload) {\n\t\t\tvar payload;\n\t\t\tif ( typeof newPayload === \"string\" ||\n\t\tnewPayload instanceof ArrayBuffer ||\n\t\t(ArrayBuffer.isView(newPayload) && !(newPayload instanceof DataView))\n\t\t\t) {\n\t\t\t\tpayload = newPayload;\n\t\t\t} else {\n\t\t\t\tthrow (format(ERROR.INVALID_ARGUMENT, [newPayload, \"newPayload\"]));\n\t\t\t}\n\n\t\t\tvar destinationName;\n\t\t\tvar qos = 0;\n\t\t\tvar retained = false;\n\t\t\tvar duplicate = false;\n\n\t\t\tObject.defineProperties(this,{\n\t\t\t\t\"payloadString\":{\n\t\t\t\t\tenumerable : true,\n\t\t\t\t\tget : function () {\n\t\t\t\t\t\tif (typeof payload === \"string\")\n\t\t\t\t\t\t\treturn payload;\n\t\t\t\t\t\telse\n\t\t\t\t\t\t\treturn parseUTF8(payload, 0, payload.length);\n\t\t\t\t\t}\n\t\t\t\t},\n\t\t\t\t\"payloadBytes\":{\n\t\t\t\t\tenumerable: true,\n\t\t\t\t\tget: function() {\n\t\t\t\t\t\tif (typeof payload === \"string\") {\n\t\t\t\t\t\t\tvar buffer = new ArrayBuffer(UTF8Length(payload));\n\t\t\t\t\t\t\tvar byteStream = new Uint8Array(buffer);\n\t\t\t\t\t\t\tstringToUTF8(payload, byteStream, 0);\n\n\t\t\t\t\t\t\treturn byteStream;\n\t\t\t\t\t\t} else {\n\t\t\t\t\t\t\treturn payload;\n\t\t\t\t\t\t}\n\t\t\t\t\t}\n\t\t\t\t},\n\t\t\t\t\"destinationName\":{\n\t\t\t\t\tenumerable: true,\n\t\t\t\t\tget: function() { return destinationName; },\n\t\t\t\t\tset: function(newDestinationName) {\n\t\t\t\t\t\tif (typeof newDestinationName === \"string\")\n\t\t\t\t\t\t\tdestinationName = newDestinationName;\n\t\t\t\t\t\telse\n\t\t\t\t\t\t\tthrow new Error(format(ERROR.INVALID_ARGUMENT, [newDestinationName, \"newDestinationName\"]));\n\t\t\t\t\t}\n\t\t\t\t},\n\t\t\t\t\"qos\":{\n\t\t\t\t\tenumerable: true,\n\t\t\t\t\tget: function() { return qos; },\n\t\t\t\t\tset: function(newQos) {\n\t\t\t\t\t\tif (newQos === 0 || newQos === 1 || newQos === 2 )\n\t\t\t\t\t\t\tqos = newQos;\n\t\t\t\t\t\telse\n\t\t\t\t\t\t\tthrow new Error(\"Invalid argument:\"+newQos);\n\t\t\t\t\t}\n\t\t\t\t},\n\t\t\t\t\"retained\":{\n\t\t\t\t\tenumerable: true,\n\t\t\t\t\tget: function() { return retained; },\n\t\t\t\t\tset: function(newRetained) {\n\t\t\t\t\t\tif (typeof newRetained === \"boolean\")\n\t\t\t\t\t\t\tretained = newRetained;\n\t\t\t\t\t\telse\n\t\t\t\t\t\t\tthrow new Error(format(ERROR.INVALID_ARGUMENT, [newRetained, \"newRetained\"]));\n\t\t\t\t\t}\n\t\t\t\t},\n\t\t\t\t\"topic\":{\n\t\t\t\t\tenumerable: true,\n\t\t\t\t\tget: function() { return destinationName; },\n\t\t\t\t\tset: function(newTopic) {destinationName=newTopic;}\n\t\t\t\t},\n\t\t\t\t\"duplicate\":{\n\t\t\t\t\tenumerable: true,\n\t\t\t\t\tget: function() { return duplicate; },\n\t\t\t\t\tset: function(newDuplicate) {duplicate=newDuplicate;}\n\t\t\t\t}\n\t\t\t});\n\t\t};\n\n\t\t// Module contents.\n\t\treturn {\n\t\t\tClient: Client,\n\t\t\tMessage: Message\n\t\t};\n\t// eslint-disable-next-line no-nested-ternary\n\t})(typeof global !== \"undefined\" ?
