Member Function Documentation

void casacore::MSReader::gotoRow

(

uInt

which

)

Go to the indicated row in the MAIN table of the MS and point at all of the appropriate rows in each of the subtables as a result of going to this row.

const MeasurementSet& casacore::MSReader::ms ( ) const

inline

Return a reference to the MS.

Definition at line 87 of file MSReader.h.

References itsMS.

MSReader& casacore::MSReader::operator= ( const MSReader &  )

private

Int casacore::MSReader::rowNumber

(

const String &

name

)

const

Return the current row number in the named table.

This returns -1 if that table has no row as a result of the most recent gotoRow.

const Table& casacore::MSReader::table

(

const String &

name

)

const

Return a reference to the named subtable.

const RecordInterface& casacore::MSReader::tableRow

(

const String &

name

)

const

Return the current row in the named table.

Use rowNumber to check to see that the most recent gotoRow actually found a matching row.
