Example 2 with ListDevicesResponse

use of com.google.api.services.cloudiot.v1.model.ListDevicesResponse in project java-docs-samples by GoogleCloudPlatform.

the class DeviceRegistryExample method clearRegistry.

// [END iot_delete_registry]
/**
 * clearRegistry
 *
 * <ul>
 *   <li>Registries can't be deleted if they contain devices,
 *   <li>Gateways (a type of device) can't be deleted if they have bound devices
 *   <li>Devices can't be deleted if bound to gateways...
 * </ul>
 *
 * To completely remove a registry, you must unbind all devices from gateways, then remove all
 * devices in a registry before removing the registry. As pseudocode: <code>
 *   ForAll gateways
 *     ForAll devicesBoundToGateway
 *       unbindDeviceFromGateway
 *   ForAll devices
 *     Delete device by ID
 *   Delete registry
 *  </code>
