Class FromJTS

java.lang.Object
  org.gvsig.fmap.geom.operation.GeometryOperation
      org.gvsig.fmap.geom.operation.fromjts.FromJTS

public class FromJTS
extends GeometryOperation

Converts a geometry from JTS to DAL format. This is a special geometry operation because don't use the Geometry parameter and returns a JTS geometry. This kind of operation can be called from the GeometryManager using invokeOperation.

This operation needs a JTS geometry loaded in the context. The only attribute of the GeometryOperation have to be a geometry of this type and the ID of this attribute will be JTSGeometry.
