| Microsoft DirectX 9.0 SDK Update (October 2004) |
The IDirectMusicTool8 interface represents a tool object that processes messages.
Methods of this interface are implemented by tools and are generally called by the performance. The application only needs to insert the tool in the message path by using IDirectMusicGraph8::InsertTool.
IDirectMusicTool8 supersedes the IDirectMusicTool interface and adds a new method.
In addition to the methods inherited from IUnknown, the IDirectMusicTool8 interface exposes the following methods.
| Method | Description |
| Clone | Creates a new instance of the tool. |
| Flush | Flushes messages from the queue when the performance stops. |
| GetMediaTypeArraySize | Retrieves the size of the array that must be passed in to the IDirectMusicTool8::GetMediaTypes method. |
| GetMediaTypes | Retrieves a list of the types of messages that this tool supports. |
| GetMsgDeliveryType | Retrieves the tool's delivery type, which determines when messages are to be delivered to the tool. |
| Init | Initializes the tool. |
| ProcessPMsg | Performs the main task of the tool. |
