Method Summary

void	loadData(InputStream input, String name) Load data from a stream.
boolean	stillAcceptsData() Check if the loader still accepts new data.

Method Detail

stillAcceptsData

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.

Returns:

true while the loader still accepts new data

loadData

void loadData(InputStream input,
              String name)
              throws IOException,

                     OrekitException

Load data from a stream.

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

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