IDirectMusicGraph

The IDirectMusicGraph 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.

The IDirectMusicGraph interface has the following methods:

Routing StampPMsg
Tools GetTool
  InsertTool
RemoveTool

All COM interfaces inherit the IUnknown interface methods. This interface supports the following three methods:

IUnknown AddRef
  QueryInterface
Release
