org.orekit.forces.gravity.potential
Class EGMFormatReader

java.lang.Object
  org.orekit.forces.gravity.potential.PotentialCoefficientsReader
      org.orekit.forces.gravity.potential.EGMFormatReader

All Implemented Interfaces:

DataLoader, PotentialCoefficientsProvider

public class EGMFormatReader
extends PotentialCoefficientsReader

This reader is adapted to the EGM Format.

The proper way to use this class is to call the GravityFieldFactory which will determine which reader to use with the selected potential coefficients file

Load data from a stream.

Specified by:

loadData in interface DataLoader

Specified by:

loadData in class PotentialCoefficientsReader

Parameters:

input - data input stream

name - name of the file (or zip entry)

Throws:

IOException - if data can't be read

ParseException - if data can't be parsed

OrekitException - if some data is missing or if some loader specific error occurs
