## 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::BasicSegmentString::BasicSegmentString | ( | geom::CoordinateSequence * | newPts,
|  | const void * | newContext
| ) |  |

inline

Construct a BasicSegmentString.

Parameters

  newPts | CoordinateSequence representing the string, externally owned
  newContext | the context associated to this SegmentString

## Member Function Documentation

int geos::noding::BasicSegmentString::getSegmentOctant | ( | unsigned int | index | ) | const

Gets the octant of the segment starting at vertex index.

Parameters

  index | the index of the vertex starting the segment. Must not be the last index in the vertex list

Returns
  the octant of the segment at the vertex
