Class FrameAdapter

java.lang.Object

org.orekit.utils.FrameAdapter

All Implemented Interfaces:

ExtendedPositionProvider, PVCoordinatesProvider

public class FrameAdapter
extends Object
implements ExtendedPositionProvider

Adapter from Frame to ExtendedPositionProvider.

The moving point is the origin of the adapted frame.

This class is roughly the inverse of ExtendedPositionProviderAdapter
