# TODO: Implement serialization/make deserialization useful.
# Deserialization was simply implemented to allow GridLocation objects to be
# passed through thrift, but the resulting Geometry object will not be transformed into
# useful data; the base byte array is passed to a worthless Geometry class.

from dynamicserialize.dstypes.com.vividsolutions.jts.geom import Geometry

# NOTE: At the moment, EDEX serializes Polygon, MultiPolygons, Points, and
# Geometrys with the tag of the base class Geometry. Java's serialization
# adapter is smarter and can determine the exact object by reading the binary
# data. This adapter doesn't need this _yet_, so it has not been implemented.
