All Implemented Interfaces:

ShapeIO, ShapeReader

public class JtsWKTReaderShapeParser
extends JtsWKTReader

This is an extension of JtsWKTReader that processes the entire string with JTS's WKTReader. Some differences:

• No support for ENVELOPE and BUFFER
• MULTI* shapes use JTS's GeometryCollection subclasses, not ShapeCollection
• 'Z' coordinates are saved into the geometry

Constructor Detail

JtsWKTReaderShapeParser

public JtsWKTReaderShapeParser(JtsSpatialContext ctx,
                               JtsSpatialContextFactory factory)

Method Detail

parseIfSupported

public Shape parseIfSupported(String wktString)
                       throws ParseException

Description copied from class: WKTReader

Parses the wktString, returning the defined Shape. If it can't because the shape name is unknown or an empty or blank string was passed, then it returns null. If the WKT starts with a supported shape but contains an inner unsupported shape then it will result in a ParseException.

Overrides:

parseIfSupported in class WKTReader

Parameters:

wktString - non-null, can be empty or have surrounding whitespace

Returns:

Shape, null if unknown / unsupported shape.

Throws:

ParseException - Thrown if there is an error in the Shape definition

parseIfSupported

protected Shape parseIfSupported(String str,
                                 com.vividsolutions.jts.io.WKTReader reader)
                          throws ParseException

Reads WKT from the str via JTS's WKTReader.

Parameters:

str -

reader -

new WKTReader(ctx.getGeometryFactory()))

Returns:

Non-Null

Throws:

ParseException

checkCoordinates

protected void checkCoordinates(com.vividsolutions.jts.geom.Geometry geom)
