# Delegates

> Comprehensive reference for Unity AI Runtime delegates, including their roles and usage scenarios.

## ProcessBaseDataIODelegate

Delegate for processing base data I/O operations from the native C++ DLL.
This callback is invoked by the native library to handle data processing events.

### Parameters

| Parameter  | Type     | Description                                                      |
| ---------- | -------- | ---------------------------------------------------------------- |
| contextPtr | `IntPtr` | Pointer to the native context object containing processing data. |

## ProcessBaseDataIODelegateExecutionID

Delegate for processing base data I/O operations that include an execution identifier.
Used when native callbacks need to distinguish between different execution contexts.

### Parameters

| Parameter   | Type     | Description                                                        |

| contextPtr  | `IntPtr` | Pointer to the native context object containing processing data.   |
| executionId | int      | The execution identifier associated with this callback invocation. |

## InworldExternalLogListener

Delegate for receiving log messages from the native C++ DLL.
Allows the managed code to capture and process logging output from the native library.

### Parameters
