public sealed class ListDeviceStatesRequest : IMessage<ListDeviceStatesRequest>, IEquatable<ListDeviceStatesRequest>, IDeepCloneable<ListDeviceStatesRequest>, IBufferMessage, IMessage
Reference documentation and code samples for the Cloud IoT v1 API class ListDeviceStatesRequest.
Required. The name of the device. For example,
projects/p0/locations/us-central1/registries/registry0/devices/device0 or
projects/p0/locations/us-central1/registries/registry0/devices/{num_id}.
The number of states to list. States are listed in descending order of
update time. The maximum number of states retained is 10. If this
value is zero, it will return all the states available.
