Client-supplied interface that provides support for buffering a group of geometries by different distances.
This interface is new at ArcGIS 9.3.
|ReadNext||Reads the next geometry (along with a client specified geometry id) and distance from the source - or returns a nil geometry when at the end.|
|WriteNext||Writes the next output buffer to its destination. The client id is valid when buffers have not been dissolved or exploded.|
