public class HduFitsTableWriter extends AbstractFitsTableWriter
TableWriter which writes a single extension BINTABLE HDU containing the table. It differs fromFitsTableWriter
in that it does not write a primary HDU, so the result will only form a legal FITS file if it is appended to an existing FITS file which already has a primary HDU, and possibly other extension HDUs already. This class can be used to generate a multi-extension FITS file.- Since:
