## Methods

### brand

**Source:** https://github.com/fastly/compute-sdk-cpp/blob/ff911e47be2f319e83a9cde960d2c3c5db534280/include/fastly/device_detection.h#L23

```cpp
std::optional<std::string> fastly::device_detection::Device::brand()
```

The brand of the client device, possibly different from the manufacturer of that device.

**Returns**

`std::optional<std::string>`

### device_name

**Source:** https://github.com/fastly/compute-sdk-cpp/blob/ff911e47be2f319e83a9cde960d2c3c5db534280/include/fastly/device_detection.h#L19

```cpp
std::optional<std::string> fastly::device_detection::Device::device_name()
```

The name of the client device.

**Returns**

`std::optional<std::string>`

### hwtype

**Source:** https://github.com/fastly/compute-sdk-cpp/blob/ff911e47be2f319e83a9cde960d2c3c5db534280/include/fastly/device_detection.h#L34

```cpp
std::optional<std::string> fastly::device_detection::Device::hwtype()
```

A string representation of the primary client platform hardware. The most commonly used device types are also identified via boolean variables. Because a device may have multiple device types and this variable only has the primary type, we recommend using the boolean variables for logic and using this string representation for logging.

**Returns**

`std::optional<std::string>`

### is_desktop

**Source:** https://github.com/fastly/compute-sdk-cpp/blob/ff911e47be2f319e83a9cde960d2c3c5db534280/include/fastly/device_detection.h#L60

```cpp
std::optional<bool> fastly::device_detection::Device::is_desktop()
```

The client is a desktop web browser.

**Returns**

`std::optional<bool>`

```cpp
std::optional<bool> fastly::device_detection::Device::is_ereader()
```

The client device is a reading device (like a Kindle).

**Returns**

`std::optional<bool>`

### is_gameconsole
