LineNoSelfIntersectValidation

public class LineNoSelfIntersectValidation extends DefaultFeatureValidation (Code)

LineNoSelfIntersectFeatureValidation purpose.

Tests to see if a geometry crosses itself. It does not detect if a segment of a LineString doubles back on itself for one segment, then terminates. A different validation is needed to test overlapping. Uses JTS' crosses routine.

Example Use:


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

Constructor Summary
public	LineNoSelfIntersectValidation() LineNoSelfIntersectFeatureValidation constructor.

Method Summary
public int	getPriority() Override getPriority. Sets the priority level of this validation.
public boolean	validate(Feature feature, FeatureType type, ValidationResults results) Override validate. Tests to see if a geometry intersects itself.

Constructor Detail

LineNoSelfIntersectValidation
public LineNoSelfIntersectValidation()(Code)
	LineNoSelfIntersectFeatureValidation constructor. Description

Method Detail

getPriority
public int getPriority()(Code)
	Override getPriority. Sets the priority level of this validation. This is set by the programmer and is a measure of the expense of this plugin A made up priority for this validation. See Also: org.geotools.validation.Validation.getPriority

validate
public boolean validate(Feature feature, FeatureType type, ValidationResults results)(Code)
	Override validate. Tests to see if a geometry intersects itself. It does not detect if a segment of a LineString doubles back on itself for one segment, then terminates. A different validation is needed to test overlapping. Uses JTS' intersect routine. Parameters: feature - The Feature to be validated. Parameters: type - The FeatureTypeInfo of the feature. Parameters: results - The storage for error messages. True if the feature does not self intersect. See Also: org.geotools.validation.FeatureValidation.validate(org.geotools.feature.Featureorg.geotools.feature.FeatureTypeInfoorg.geotools.validation.ValidationResults)
