Constructor & Destructor Documentation

casacore::MSPrimaryTableHolder::MSPrimaryTableHolder

(

)

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

Construct an empty holder, used to attach to later

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
