Author:

Julian J. Ray

To Do:

Add interior polygons to Polygon constructor, Add support multi-polygon types, Add support for GeoMedia Arcs

Constructor Summary

GeoMediaGeometryAdapter()
Creates a new GeoMediaGeometryAdapter object.

Method Summary

com.vividsolutions.jts.geom.Geometry	deSerialize(byte[] input) Converts GeoMedia blobs to JTS geometry types.
byte[]	serialize(com.vividsolutions.jts.geom.Geometry input) Converts a JTS geometry to a GeoMedia geometry blob which can be stored in a geomedia spatial database.

                                                        GeoMediaUnsupportedGeometryTypeException

Converts GeoMedia blobs to JTS geometry types. Performs endian-conversion on data contained in the blob.

Parameters:

input - GeoMedia geometry blob read from geomedia spatial database.

Returns:

JTS Geometry

Throws:

java.io.IOException

GeoMediaGeometryTypeNotKnownException

GeoMediaUnsupportedGeometryTypeException

serialize

public byte[] serialize(com.vividsolutions.jts.geom.Geometry input)
                 throws java.io.IOException,
                        GeoMediaUnsupportedGeometryTypeException

Converts a JTS geometry to a GeoMedia geometry blob which can be stored in a geomedia spatial database.

Parameters:

input - JTS Geometry

Returns:

byte[] GeoMedia blob format

Throws:

java.io.IOException

GeoMediaUnsupportedGeometryTypeException
