Detailed Description
Represents a list of contiguous line segments, and supports noding the segments.
The line segments are represented by an array of Coordinates. Intended to optimize the noding of contiguous segments by reducing the number of allocated objects. SegmentStrings can carry a context object, which is useful for preserving topological or parentage information. All noded substrings are initialized with the same context object.

Constructor & Destructor Documentation
| geos::noding::NodedSegmentString::NodedSegmentString | ( | geom::CoordinateSequence * | newPts, | |
| const void * | newContext | |||
| ) | [inline] |
Creates a new segment string from a list of vertices.
- Parameters:
-
pts the vertices of the segment string data the user-defined data of this segment string (may be null)
Member Function Documentation
| SegmentNode* geos::noding::NodedSegmentString::addIntersectionNode | ( | geom::Coordinate * | intPt, | |
| int | segmentIndex | |||
| ) | [inline] |
Adds an intersection node for a given point and segment to this segment string. If an intersection already exists for this exact location, the existing node will be returned.
- Parameters:
-
intPt the location of the intersection segmentIndex the index of the segment containing the intersection
- Returns:
- the intersection node for the point
