Class FitsTableWriter
java.lang.Object
uk.ac.starlink.table.StreamStarTableWriter
uk.ac.starlink.fits.AbstractFitsTableWriter
uk.ac.starlink.fits.FitsTableWriter
- All Implemented Interfaces:
- MultiStarTableWriter, StarTableWriter
public class FitsTableWriter
- extends AbstractFitsTableWriter
Handles writing of a StarTable in FITS binary format.
Not all columns can be written to a FITS table, only those ones
whose contentClass is in the following list:
- Boolean
- Character
- Byte
- Short
- Integer
- Long
- Float
- Double
- Character
- String
- boolean[]
- char[]
- byte[]
- short[]
- int[]
- long[]
- float[]
- double[]
- String[]
In all other cases a warning message will be logged and the column
will be ignored for writing purposes.
Output is currently to fixed-width columns only. For StarTable columns
of variable size, a first pass is made through the table data to
determine the largest size they assume, and the size in the output
table is set to the largest of these. Excess space is padded
with some sort of blank value (NaN for floating point values,
spaces for strings, zero-like values otherwise).
