## Member Function Documentation

SegmentNode* geos::noding::SegmentNodeList::add | ( | const geom::Coordinate & | intPt,
|  | size_t | segmentIndex |
| ) |  |  |

Adds an intersection into the list, if it isn't already there. The input segmentIndex is expected to be normalized.

Returns:
  the SegmentIntersection found or added. It will be destroyed at SegmentNodeList destruction time.

Parameters:

  | intPt | the intersection Coordinate, will be copied
  | segmentIndex |

void geos::noding::SegmentNodeList::addEndpoints | ( |  | ) |

Adds entries for the first and last points of the edge to the list

void geos::noding::SegmentNodeList::addSplitEdges | ( | std::vector< SegmentString * > & | edgeList | ) |

Creates new edges for all the edges that the intersections in this list split the parent edge into. Adds the edges to the input list (this is so a single list can be used to accumulate all split edges for a Geometry).
