Class MathTransformExport

java.lang.Object
  java.rmi.server.RemoteObject
      org.deegree_impl.model.ct.MathTransformExport

All Implemented Interfaces:

CT_MathTransform, java.rmi.Remote, java.io.Serializable

final class MathTransformExport

extends java.rmi.server.RemoteObject

implements CT_MathTransform

Wrap a MathTransform for use with OpenGIS. This wrapper is a good place to check for non-implemented OpenGIS methods (just check for methods throwing UnsupportedOperationException). This class is suitable for RMI use.

Returns:

flags classifying domain points within the convex hull.

Throws:

java.rmi.RemoteException - if a remote method call failed.

getCodomainConvexHull
