Class GRGSFormatReader

java.lang.Object

fr.cnes.sirius.patrius.forces.gravity.potential.PotentialCoefficientsReader

fr.cnes.sirius.patrius.forces.gravity.potential.GRGSFormatReader

All Implemented Interfaces:

DataLoader, PotentialCoefficientsProvider, Serializable

public class GRGSFormatReader
extends PotentialCoefficientsReader

Reader for the GRGS gravity field format.

This format was used to describe various gravity fields at GRGS (Toulouse).

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

GRGSFormatReader

public GRGSFormatReader(String supportedNames,
                        boolean missingCoefficientsAllowed)

Simple constructor.

Parameters:

supportedNames - regular expression for supported files names

missingCoefficientsAllowed - if true, allows missing coefficients in the input data

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

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