org.gvsig.fmap.geom.jts.operation.fromwkb.WKBParser2

public class WKBParser2
extends Object

Parse binary representation of geometries. Currently, only text rep (hexed) implementation is tested. It should be easy to add char[] and CharSequence ByteGetter instances, although the latter one is not compatible with older jdks. I did not implement real unsigned 32-bit integers or emulate them with long, as both java Arrays and Strings currently can have only 2^31-1 elements (bytes), so we cannot even get or build Geometries with more than approx. 2^28 coordinates (8 bytes each).

Method Details

parse

public org.gvsig.fmap.geom.Geometry parse(byte[] value)
                                   throws org.gvsig.fmap.geom.exception.CreateGeometryException

Parse a binary encoded geometry. Is synchronized to protect offset counter. (Unfortunately, Java does not have neither call by reference nor multiple return values.)

Throws:

org.gvsig.fmap.geom.exception.CreateGeometryException

parseTypeAndSRID

protected void parseTypeAndSRID(ByteBuffer data)

parseGeometry

protected org.gvsig.fmap.geom.Geometry parseGeometry(ByteBuffer data)
                                              throws org.gvsig.fmap.geom.exception.CreateGeometryException

Parse a geometry starting at offset.

Throws:

org.gvsig.fmap.geom.exception.CreateGeometryException
