Class LengthSubstring

java.lang.Object

com.vividsolutions.jump.algorithm.LengthSubstring

public class LengthSubstring
extends java.lang.Object

Computes a substring of a LineString between given distances along the line.

• The distances are clipped to the actual line length
• If the start distance is equal to the end distance, a zero-length line with two identical points is returned
• FUTURE: If the start distance is greater than the end distance, an inverted section of the line is returned

FUTURE: should handle startLength > endLength, and flip the returned linestring. Also should handle negative lengths (they are measured from end of line backwards).
