Class ColFitsStarTable

java.lang.Object
uk.ac.starlink.table.AbstractStarTable
uk.ac.starlink.fits.ColFitsStarTable
All Implemented Interfaces:
Closeable, AutoCloseable, uk.ac.starlink.table.StarTable
public class ColFitsStarTable extends uk.ac.starlink.table.AbstractStarTable
StarTable based on a single-row FITS BINTABLE which contains the data for an entire column in each cell of the table. The BINTABLE must be the first extension of a FITS file.

Some instances of this class hang on to file descriptors. If you are in danger of running out of that resource before insstances are garbage collected, you can call the close() method to release them. Attempting to read data following such a call may result in an exception.
