java.lang.Objectuk.ac.starlink.fits.StandardFitsTableSerializer
public class StandardFitsTableSerializer
Class which knows how to do the various bits of serializing a StarTable to FITS BINTABLE format. A normal (row-oriented) organisation of the data is used. Array-valued columns are all written as fixed size arrays. This class does the hard work for FitsTableWriter.

StandardFitsTableSerializer(StarTable table,
boolean allowSignedByte,
WideFits wide)
Constructs a serializer to write a given StarTable, with explicit instruction about how to write byte-type columns data. |
