![](https://img.shields.io/badge/-public-brightgreen "public")

```cpp
rtidds::GenericBytesMessage simulation_framework::autonomy::communication::utils::CreateDdsMessageFromOsiProto(const int frame_counter, const std::string &header_name, const OsiProtoType &osi_proto_msg)

```

Converts an OSI proto message to a DDS GenericBytesMessage.

`parameterlist {"type":"element","name":"parameterlist","attributes":{"kind":"templateparam"},"children":[{"type":"element","name":"parameteritem","attributes":{},"children":[{"type":"text","text":"\n"},{"type":"element","name":"parameternamelist","attributes":{},"children":[{"type":"text","text":"\n"},{"type":"element","name":"parametername","attributes":{},"children":[{"type":"text","text":"OsiProtoType"}]},{"type":"text","text":"\n"}]},{"type":"text","text":"\n"},{"type":"element","name":"parameterdescription","attributes":{},"children":[{"type":"text","text":"\n"},{"type":"element","name":"para","attributes":{},"children":[{"type":"text","text":"The OSI proto message type (e.g., osi3::SensorView, osi3::SensorData, osi3::TrafficUpdate) "}]},{"type":"text","text":"\n"}]},{"type":"text","text":"\n"}]},{"type":"text","text":"\n"}]}`

**Parameters**:

- **frame\_counter**: The frame counter for the message
- **header\_name**: The header name to use for the DDS message (e.g., "SensorView", "SensorData", "TrafficUpdate", "MotionRequest")
- **osi\_proto\_msg**: The OSI proto message to convert

**Returns**:

A GenericBytesMessage containing the serialized OSI proto message

?&gt; The OsiProtoType must have:

```cpp
void simulation_framework::autonomy::communication::utils::ParseOsiProtoFromDdsMessage(const rtidds::GenericBytesMessage &dds_msg, OsiProtoType &osi_proto_msg)

```

Converts a DDS GenericBytesMessage back to an OSI proto message.

`parameterlist {"type":"element","name":"parameterlist","attributes":{"kind":"templateparam"},"children":[{"type":"element","name":"parameteritem","attributes":{},"children":[{"type":"text","text":"\n"},{"type":"element","name":"parameternamelist","attributes":{},"children":[{"type":"text","text":"\n"},{"type":"element","name":"parametername","attributes":{},"children":[{"type":"text","text":"OsiProtoType"}]},{"type":"text","text":"\n"}]},{"type":"text","text":"\n"},{"type":"element","name":"parameterdescription","attributes":{},"children":[{"type":"text","text":"\n"},{"type":"element","name":"para","attributes":{},"children":[{"type":"text","text":"The OSI proto message type (e.g., osi3::SensorView, osi3::SensorData, osi3::TrafficUpdate) "}]},{"type":"text","text":"\n"}]},{"type":"text","text":"\n"}]},{"type":"text","text":"\n"}]}`

**Parameters**:

- **dds\_msg**: The DDS GenericBytesMessage to convert
- **osi\_proto\_msg**: Reference to the OSI proto message to populate

**Exceptions**:

- **std::runtime\_error**: If parsing fails

?&gt; The OsiProtoType must have:
