ColFitsTableWriter (Starjava FITS API)

java.lang.Object
- uk.ac.starlink.table.StreamStarTableWriter
- - uk.ac.starlink.fits.AbstractFitsTableWriter
  - - uk.ac.starlink.fits.ColFitsTableWriter

All Implemented Interfaces:

uk.ac.starlink.table.MultiStarTableWriter, uk.ac.starlink.table.StarTableWriter
```
public class ColFitsTableWriter
extends AbstractFitsTableWriter
```
Handles writing of a StarTable in a 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.

```
    Description copied from class: AbstractFitsTableWriter
    
    Provides a suitable serializer for a given table. Note this should throw an IOException if it can be determined that the submitted table cannot be written by this writer, for instance if it has too many columns.
