The following host interfaces are passed as function arguments and are thus also
implemented for serialization purposes:
| yabridge class | Interfaces | Notes |
| -------------------- | ------------------- | ---------------------------------------------------------------------- |
| `YaAttributeList` | `IAttributeList` | |
| `YaEventList` | `IEventList` | Comes with a lot of serialization wrappers around the related structs. |
| `YaMessage` | `IMessage` | |
| `YaMessagePtr` | `IMessage` | Should be used in inter process communication to exchange messages |
| `YaParameterChanges` | `IParameterChanges` | |
| `YaParamValueQueue` | `IParamValueQueue` | |
| `VectorStream` | `IBStream` | Used for serializing data streams. |
| yabridge class | Interfaces | Notes |
| --------------------- | -------------------- | --------------------------------------------------------------------- |
| `YaAttributeList` | `IAttributeList` | |
| `YaContextMenuTarget` | `IContextMenuTarget` | Used in `YaContextMenu` to proxy specific menu items |
| `YaEventList` | `IEventList` | Comes with a lot of serialization wrappers around the related structs |
| `YaMessage` | `IMessage` | |
| `YaMessagePtr` | `IMessage` | Should be used in inter process communication to exchange messages |
| `YaParameterChanges` | `IParameterChanges` | |
| `YaParamValueQueue` | `IParamValueQueue` | |
| `VectorStream` | `IBStream` | Used for serializing data streams |
And finally `YaProcessData` uses the above along with `YaAudioBusBuffers` to
wrap around `ProcessData`.
