Class OdmParser<T extends NdmConstituent<OdmHeader,?>,P extends OdmParser<T,?>>

java.lang.Object

org.orekit.files.ccsds.utils.parsing.AbstractMessageParser<T>

org.orekit.files.ccsds.utils.parsing.AbstractConstituentParser<OdmHeader,T,P>

org.orekit.files.ccsds.ndm.odm.OdmParser<T,P>

Type Parameters:

T - type of the ODM file

P - type of the parser

All Implemented Interfaces:

MessageParser<T>

Direct Known Subclasses:

OcmParser, OemParser, OmmParser, OpmParser

public abstract class OdmParser<T extends NdmConstituent<OdmHeader,?>,P extends OdmParser<T,?>>
extends AbstractConstituentParser<OdmHeader,T,P>

Common parser for Orbit Parameter/Ephemeris/Mean/Comprehensive Messages.

Note than starting with Orekit 11.0, CCSDS message parsers are mutable objects that gather the data being parsed, until the message is complete and the parseMessage method has returned. This implies that parsers should not be used in a multi-thread context. The recommended way to use parsers is to either dedicate one parser for each message and drop it afterwards, or to use a single-thread loop.

Since:

11.0

OdmParser

protected OdmParser(String root,
                    String formatVersionKey,
                    IERSConventions conventions,
                    boolean simpleEOP,

                    ParsedUnitsBehavior parsedUnitsBehavior,
                    Function<ParseToken,List<ParseToken>>[] filters)

Complete constructor.

Parameters:

root - root element for XML files

formatVersionKey - key for format version

conventions - IERS Conventions

simpleEOP - if true, tidal effects are ignored when interpolating EOP

dataContext - used to retrieve frames and time scales

missionReferenceDate - reference date for Mission Elapsed Time or Mission Relative Time time systems

mu - gravitational coefficient

parsedUnitsBehavior - behavior to adopt for handling parsed units

filters - filters to apply to parse tokens

Since:

12.0

Method Detail

getMissionReferenceDate

public AbsoluteDate getMissionReferenceDate()

Get reference date for Mission Elapsed Time and Mission Relative Time time systems.

Returns:

the reference date

getMuSet

protected double getMuSet()

Get the gravitational coefficient set at construction.

Returns:

gravitational coefficient set at construction

setMuParsed

protected void setMuParsed(double muParsed)

Set the gravitational coefficient parsed in the ODM File.

Parameters:

muParsed - the coefficient to be set

setMuCreated

protected void setMuCreated(double muCreated)

Set the gravitational coefficient created from the knowledge of the central body.

Parameters:

muCreated - the coefficient to be set

getSelectedMu

public double getSelectedMu()

Select the gravitational coefficient to use. In order of decreasing priority, finalMU is set equal to:

1. the coefficient parsed in the file,
2. the coefficient set by the user with the parser's method setMu,
3. the coefficient created from the knowledge of the central body.

Returns:

selected gravitational coefficient
