Class LineMerger

    java.lang.Object
      com.vividsolutions.jts.operation.linemerge.LineMerger

public class LineMerger
extends java.lang.Object

Sews together a set of fully noded LineStrings. Sewing stops at nodes of degree 1 or 3 or more -- the exception is an isolated loop, which only has degree-2 nodes, in which case a node is simply chosen as a starting point. The direction of each merged LineString will be that of the majority of the LineStrings from which it was derived.

Any dimension of Geometry is handled -- the constituent linework is extracted to form the edges. The edges must be correctly noded; that is, they must only meet at their endpoints. The LineMerger will still run on incorrectly noded input but will not form polygons from incorrected noded edges.

NOTE:once merging has been performed, no more
