  org.geotools.validation.DefaultFeatureValidation
      org.geotools.validation.spatial.LineMustBeASinglePartValidation

All Implemented Interfaces:

FeatureValidation, Validation

public class LineMustBeASinglePartValidation

extends DefaultFeatureValidation

LineIsSingleSegmentFeatureValidation purpose.

Tests to see if a LineString is made of only one segment, meaning it only has two points. If the LineString has more than two points, the test fails.

This method has been extended to work with MultiLineStrings - this is the most common format that shapefile appears in and as such is forcing our hand.

Example Use:

 LineIsSingleSegmentFeatureValidation x = new LineIsSingleSegmentFeatureValidation("noSelfIntersectRoads", "Tests to see if a 
 geometry intersects itself", new String[] {"road"});
