## Detailed Description

A list of the SegmentNode present along a NodedSegmentString.

## Member Function Documentation

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

The documentation for this class was generated from the following file:
