Class NamedCoordinateReferenceSystemConverter

java.lang.Object

org.mongodb.morphia.converters.TypeConverter

org.mongodb.morphia.geo.NamedCoordinateReferenceSystemConverter

All Implemented Interfaces:

SimpleValueConverter

public class NamedCoordinateReferenceSystemConverter
extends TypeConverter
implements SimpleValueConverter

A Morphia TypeConverter that knows how to turn things that are labelled with the Geometry interface into the correct concrete class, based on the GeoJSON type.

Only implements the decode method as the concrete classes can encode themselves without needing a converter. It's when they come out of the database that there's not enough information for Morphia to automatically create Geometry instances.
