Detailed Description

A helper class for MSFitsInput.

Intended use:

Internal

Etymology

This class can hold a primary group of several datatypes

Synopsis

This is a helper class to avoid cumbersome switch statements on the template type of the primary group It forwards all the PrimaryGroup member functions we need in the filler.

Constructor & Destructor Documentation

casacore::MSPrimaryGroupHolder::MSPrimaryGroupHolder ( )

This is a helper class to avoid cumbersome switch statements on the template type of the primary group It forwards all the PrimaryGroup member function we need in the filler.

Construct an empty holder, used to attach to later

casacore::MSPrimaryGroupHolder::MSPrimaryGroupHolder ( FitsInput infile)

Construct from an input file containing a FITS primary group hdu.

Throws an exception if the datatype is not Short, FitsLong or Float
