    public interface DeviceConfigOrBuilder extends MessageOrBuilder

## Implements

[MessageOrBuilder](https://cloud.google.com/java/docs/reference/protobuf/latest/com.google.protobuf.MessageOrBuilder.html)

## Methods

### getBinaryData()

    public abstract ByteString getBinaryData()

The device configuration data.

`bytes binary_data = 4;`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://cloud.google.com/java/docs/reference/protobuf/latest/com.google.protobuf.ByteString.html` | The binaryData. |

### getCloudUpdateTime()

    public abstract Timestamp getCloudUpdateTime()

\[Output only\] The time at which this configuration version was updated in
Cloud IoT Core. This timestamp is set by the server.

`.google.protobuf.Timestamp cloud_update_time = 2;`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://cloud.google.com/java/docs/reference/protobuf/latest/com.google.protobuf.Timestamp.html` | The cloudUpdateTime. |

### getCloudUpdateTimeOrBuilder()

    public abstract TimestampOrBuilder getCloudUpdateTimeOrBuilder()

\[Output only\] The time at which this configuration version was updated in
Cloud IoT Core. This timestamp is set by the server.

`.google.protobuf.Timestamp cloud_update_time = 2;`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://cloud.google.com/java/docs/reference/protobuf/latest/com.google.protobuf.TimestampOrBuilder.html` |   |

### getDeviceAckTime()

    public abstract Timestamp getDeviceAckTime()

\[Output only\] The time at which Cloud IoT Core received the
acknowledgment from the device, indicating that the device has received
this configuration version. If this field is not present, the device has
not yet acknowledged that it received this version. Note that when
the config was sent to the device, many config versions may have been
available in Cloud IoT Core while the device was disconnected, and on
connection, only the latest version is sent to the device. Some
versions may never be sent to the device, and therefore are never
acknowledged. This timestamp is set by Cloud IoT Core.

`.google.protobuf.Timestamp device_ack_time = 3;`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://cloud.google.com/java/docs/reference/protobuf/latest/com.google.protobuf.Timestamp.html` | The deviceAckTime. |

### getDeviceAckTimeOrBuilder()

    public abstract TimestampOrBuilder getDeviceAckTimeOrBuilder()

\[Output only\] The time at which Cloud IoT Core received the
acknowledgment from the device, indicating that the device has received
this configuration version. If this field is not present, the device has
not yet acknowledged that it received this version. Note that when
the config was sent to the device, many config versions may have been

`.google.protobuf.Timestamp device_ack_time = 3;`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://cloud.google.com/java/docs/reference/protobuf/latest/com.google.protobuf.TimestampOrBuilder.html` |   |

### getVersion()

    public abstract long getVersion()

\[Output only\] The version of this update. The version number is assigned by
the server, and is always greater than 0 after device creation. The
version must be 0 on the `CreateDevice` request if a `config` is
specified; the response of `CreateDevice` will always have a value of 1.

`int64 version = 1;`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html` | The version. |

### hasCloudUpdateTime()

    public abstract boolean hasCloudUpdateTime()

\[Output only\] The time at which this configuration version was updated in
Cloud IoT Core. This timestamp is set by the server.

`.google.protobuf.Timestamp cloud_update_time = 2;`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html` | Whether the cloudUpdateTime field is set. |

### hasDeviceAckTime()

    public abstract boolean hasDeviceAckTime()

\[Output only\] The time at which Cloud IoT Core received the
acknowledgment from the device, indicating that the device has received
this configuration version. If this field is not present, the device has
not yet acknowledged that it received this version. Note that when
the config was sent to the device, many config versions may have been

`.google.protobuf.Timestamp device_ack_time = 3;`

| **Returns** ||
|---|---|
| **Type** | **Description** |
| `https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html` | Whether the deviceAckTime field is set. |
