Class PostgisWkbEncoder

java.lang.Object

org.geolatte.geom.codec.PostgisWkbEncoder

All Implemented Interfaces:

WkbEncoder

Direct Known Subclasses:

PostgisWkbV2Encoder

public class PostgisWkbEncoder
extends Object
implements WkbEncoder

A WKBEncoder for the PostGIS EWKB dialect (for Postgis versions < 2.2.2).

This WKBEncoder encodes empty points as empty GeometryCollections. This convention was changed in Postgis version 2.2.2 to an encoding with NaN coordinates. For the later convention use the PostgisWkbV2Encoder
