Member Function Documentation

void SDTSPolygonReader::AssembleRings ( SDTSTransfer poTransfer,
int  iPolyLayer 
)

Assemble geometry for a polygon transfer.

This method takes care of attaching lines from all the line layers in this transfer to this polygon layer, assembling the lines into rings on the polygons, and then cleaning up unnecessary intermediate results.

Currently this method will leave the line layers rewound to the beginning but indexed, and the polygon layer rewound but indexed. In the future it may restore reading positions, and possibly flush line indexes if they were not previously indexed.

This method does nothing if the rings have already been assembled on this layer using this method.

See SDTSRawPolygon::AssembleRings() for more information on how the lines are assembled into rings.

Parameters:
poTransfer the SDTSTransfer that this reader is a part of. Used to get a list of line layers that might be needed.
iPolyLayer the polygon reader instance number, used to avoid processing lines for other layers.
