Method Detail
-
getAbscissaGrid
public double[] getAbscissaGrid()
Returns a copy of the abscissa grid for the interpolation function.- Returns:
- the abscissa grid for the interpolation function,
or
null
if the file could not be read
-
getOrdinateGrid
public double[] getOrdinateGrid()
Returns a copy of the ordinate grid for the interpolation function.- Returns:
- the ordinate grid for the interpolation function,
or
null
if the file could not be read
-
getValuesSamples
public double[][] getValuesSamples()
Returns a copy of the values samples for the interpolation function.- Returns:
- the values samples for the interpolation function,
or
null
if the file could not be read
-
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 interfaceDataLoader
- Returns:
- true while the loader still accepts new data

loadData
public void loadData(InputStream input, String name) throws IOException, ParseException
Loads an bi-variate interpolation table from the givenInputStream
. The format of the table is as follows (number of rows/columns can be extended):Table: tableName | 0.0 | 60.0 | 66.0 ------------------------- 0 | 0.0 | 0.003 | 0.006 500 | 0.0 | 0.003 | 0.006
- Specified by:
loadData
in interfaceDataLoader
- Parameters:
input
- the input stream to read data fromname
- the name of the input file- Throws:
IOException
- if data can't be readParseException
- if data can't be parsed
