ColFitsStarTable (Starjava FITS API)

java.lang.Object
- uk.ac.starlink.table.AbstractStarTable
- - uk.ac.starlink.fits.ColFitsStarTable

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable
```
public class ColFitsStarTable
extends uk.ac.starlink.table.AbstractStarTable
implements java.io.Closeable
```
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.

    Constructor.
    
    Parameters:
    
    datsrc - data source containing the FITS data
    
    hdr - header of the HDU containing the table
    
    dataPos - offset into file of the start of the data part of the HDU
    
    force - true to make a table if we possibly can, false to reject if it doesn't look very much like one
    
    wide - convention for representing extended columns; use null to avoid use of extended columns
    
    Throws:
    
    java.io.IOException
