| /** |
| * Conversion functions |
| * ==================== |
| * |
| * There are two main directions of conversion: |
| * - `inTargetType(...)`: Create a wrapper whose lifetime depends on the |
| * input. The wrapper has type `TargetType`. |
| * - `toTargetType(...)`: Create a standalone object of type `TargetType` that |
| * corresponds to the input. The lifetime of the output does not depend on the |
| * lifetime of the input. |
| * - `wrapIn(TargetType*, ...)`: Same as `inTargetType()`, but for `TargetType` |
| * that cannot be copied and/or moved efficiently, or when there are multiple |
| * output arguments. |
| * - `convertTo(TargetType*, ...)`: Same as `toTargetType()`, but for |
| * `TargetType` that cannot be copied and/or moved efficiently, or when there |
| * are multiple output arguments. |
| * |
| * `wrapIn()` and `convertTo()` functions will take output arguments before |
| * input arguments. Some of these functions might return a value to indicate |
| * success or error. |
| * |
| * In converting or wrapping something as a Treble type that contains a |
| * `hidl_handle`, `native_handle_t*` will need to be created and returned as |
| * an additional output argument, hence only `wrapIn()` or `convertTo()` would |
| * be available. The caller must call `native_handle_delete()` to deallocate the |
| * returned native handle when it is no longer needed. |
| * |
| * For types that contain file descriptors, `inTargetType()` and `wrapAs()` do |
| * not perform duplication of file descriptors, while `toTargetType()` and |
| * `convertTo()` do. |
