Class ColFitsTableBuilder

java.lang.Object
uk.ac.starlink.table.formats.DocumentedTableBuilder
uk.ac.starlink.fits.ColFitsTableBuilder
All Implemented Interfaces:
uk.ac.starlink.table.Documented, uk.ac.starlink.table.formats.DocumentedIOHandler, uk.ac.starlink.table.TableBuilder

public class ColFitsTableBuilder extends uk.ac.starlink.table.formats.DocumentedTableBuilder
Implementation of the TableBuilder interface which reads tables stored in column-oriented FITS binary table format. The table data is stored in a BINTABLE extension which has a single row; each cell in this row contains the data for an entire column of the represented table.

This rather specialised format may provide good performance for certain operations on very large, especially very wide, tables. Although it is FITS and can therefore be used in principle for data interchange, in practice most non-STIL processors are unlikely to be able to do much useful with it.
