Member Function Documentation

◆ gotoRow()

void casacore::MSReader::gotoRow ( rownr_t  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.

◆ ms()

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

Return a reference to the MS.

Definition at line 87 of file MSReader.h.

◆ operator=()

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

◆ rowNumber()

Int64 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.

◆ table()

const Table& casacore::MSReader::table ( const String &  name) const

Return a reference to the named subtable.

◆ tableRow()

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.
