public class RapidDataAndPredictionColumnsLoader extends Object implements EOP1980HistoryLoader, EOP2000HistoryLoader
Rapid data and prediction files contain Earth Orientation Parameters
for several years periods, in one file only that is updated regularly.
These files contain both the data from IERS Bulletin A and IERS bulletin B. This class parses only the part from Bulletin A.
The rapid data and prediction file is recognized thanks to its base name, which must match one of the the patterns
finals.*
or finals2000A.*
(or the same ending with .gz
for gzip-compressed
files) where * stands for a word like "all", "daily", or "data". The file with 2000A in their name correspond to the
IAU-2000 precession-nutation model whereas the files without any identifier correspond to the IAU-1980
precession-nutation model. The files with the all suffix start from 1973-01-01, the file with the data suffix start
from 1992-01-01 and the files with the daily suffix.

supportedNamesIn
- regular expression for supported files namespublic boolean stillAcceptsData()
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.
