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.

Version:

1.7

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
