* Constructs a service interface object. Each API operation is exposed as a

|
* function on service.
|
||
|
|
*
|
||
|
|
* ### Sending a Request Using IotData
|
||
|
|
*
|
||
|
|
* ```javascript
|
||
|
|
* var iotdata = new AWS.IotData({endpoint: 'my.host.tld'});
|
||
|
|
* iotdata.getThingShadow(params, function (err, data) {
|
||
|
|
* if (err) console.log(err, err.stack); // an error occurred
|
||
|
|
* else console.log(data); // successful response
|
||
|
|
* });
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ### Locking the API Version
|
||
|
|
*
|
||
|
|
* In order to ensure that the IotData object uses this specific API,
|
||
|
|
* you can construct the object by passing the `apiVersion` option to the
|
||
|
|
* constructor:
|
||
|
|
*
|
||
|
|
* ```javascript
|
||
|
|
* var iotdata = new AWS.IotData({
|
||
|
|
* endpoint: 'my.host.tld',
|
||
|
|
* apiVersion: '2015-05-28'
|
||
|
|
* });
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* You can also set the API version globally in `AWS.config.apiVersions` using
|
||
|
|
* the **iotdata** service identifier:
|
||
|
|
*
|
||
|
|
* ```javascript
|
||
|
|
* AWS.config.apiVersions = {
|
||
|
|
* iotdata: '2015-05-28',
|
||
|
|
* // other service API versions
|
||
|
|
* };
|
||
|
|
*
|
||
|
|
* var iotdata = new AWS.IotData({endpoint: 'my.host.tld'});
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* @note You *must* provide an `endpoint` configuration parameter when
|
||
|
|
* constructing this service. See {constructor} for more information.
|
||
|
|
*
|
||
|
|
* @!method constructor(options = {})
|
||
|
|
* Constructs a service object. This object has one method for each
|
||
|
|
* API operation.
|
||
|
|
*
|
||
|
|
* @example Constructing a IotData object
|
||
|
|
* var iotdata = new AWS.IotData({endpoint: 'my.host.tld'});
|
||
|
|
* @note You *must* provide an `endpoint` when constructing this service.
