IDirectMusicGraph8 Interface
The IDirectMusicGraph8 interface manages the loading and message flow of tools.
Graphs can occur in two places: performances and segments. The graph of tools in a performance is global in nature; it processes messages from all segments. A graph in a segment exists only for playback of that segment.
IDirectMusicGraph8 is a type definition for IDirectMusicGraph. The two interface names are interchangeable.
In addition to the methods inherited from IUnknown, the IDirectMusicGraph8 interface exposes the following methods.
| Method | Description |
| GetTool | Retrieves a tool by index. |
| InsertTool | Inserts a tool in the graph. |
| RemoveTool | Removes a tool from the graph. |
| StampPMsg | Stamps a message with a pointer to the next tool that is to receive it. |
