loadData

Constructor Detail

OceanTidesReader

public OceanTidesReader(String supportedNames)

Simple constructor.

Parameters:

supportedNames - regular expression for supported files names

Method Detail

getSupportedNames

public String getSupportedNames()

Get the regular expression for supported files names.

Returns:

regular expression for supported files names

setMaxParseDegree

public void setMaxParseDegree(int maxParseDegree)

Set the degree limit for the next file parsing.

Parameters:

maxParseDegree - maximal degree to parse (may be safely set to Integer.MAX_VALUE to parse all available coefficients)

getMaxParseDegree

public int getMaxParseDegree()

Get the degree limit for the next file parsing.

Returns:

degree limit for the next file parsing

setMaxParseOrder

public void setMaxParseOrder(int maxParseOrder)

Set the order limit for the next file parsing.

Parameters:

maxParseOrder - maximal order to parse (may be safely set to Integer.MAX_VALUE to parse all available coefficients)

getMaxParseOrder

public int getMaxParseOrder()

Get the order limit for the next file parsing.

Returns:

order limit for the next file parsing

stillAcceptsData

public boolean stillAcceptsData()

Check if the loader still accepts new data.

This method is used to speed up data loading by interrupting crawling the data sets as soon as a loader has found the data it was waiting for. For loaders that can merge data from any number of sources (for example JPL ephemerides or Earth Orientation Parameters that are split among several files), this method should always return true to make sure no data is left over.

Specified by:

stillAcceptsData in interface DataLoader

Returns:

true while the loader still accepts new data

startParse

protected void startParse(String fileName)

Start parsing.

This method must be called by subclasses when they start parsing a file

Parameters:

fileName - name of the file (or zip entry)

canAdd

public boolean canAdd(int n,
             int m)

Check if coefficients can be added.

Parameters:

n - degree of the coefficients

m - order of the coefficients

Returns:

true if coefficients can be added

addWaveCoefficients

protected void addWaveCoefficients(int doodson,
                       int n,
                       int m,
                       double cPlus,
                       double sPlus,
                       double cMinus,
                       double sMinus,
                       int lineNumber,
                       String line)
                            throws OrekitException

Add parsed coefficients.

Parameters:

doodson - Doodson number of the current wave

n - degree of the coefficients

m - order of the coefficients

cPlus - C+(n,m)

sPlus - S+(n,m)

cMinus - C-(n,m)

sMinus - S-(n,m)

lineNumber - number of the parsed line

line - text of the line

Throws:

OrekitException - if coefficients for waves are interleaved

endParse

protected void endParse()
                 throws OrekitException

End parsing.

This method must be called by subclasses when they end parsing a file

Throws:

OrekitException - if expected degree and order were not met

getWaves

public List<OceanTidesWave> getWaves()

Get the loaded waves.

Returns:

loaded waves
