Example 36 with TwinState

use of com.microsoft.azure.sdk.iot.deps.twin.TwinState in project azure-iot-sdk-java by Azure.

the class DeviceTwin method updateTwin.

/**
 * This method updates device twin for the specified device.
 * <p>This API uses the IoT Hub PATCH API when sending updates, but it sends the full twin with each patch update.
 * As a result, devices subscribed to twin will receive notifications that each property is changed when this API is
 * called, even if only some of the properties were changed.</p>
 * <p>See <a href="https://docs.microsoft.com/en-us/rest/api/iothub/service/devices/updatetwin">PATCH</a> for
 * more details.</p>
 *
 * @param device The device with a valid Id for which device twin is to be updated.
 * @throws IOException This exception is thrown if the IO operation failed.
 * @throws IotHubException This exception is thrown if the response verification failed.
