Get the quantum in the specified row, converted to the given unit. Get the quantum in the specified row, converted to the unit in other. Return the quantum stored in the specified row, converted to the given unit. Return the quantum in the specified row, converted to the unit in other. An empty string is returned if the column has variable units.
Assignment makes no sense in a read only class.
Declaring this operator private makes it unusable. Comparison is not defined, since its semantics are unclear. Called by destructor and any member which needs to reallocate data. The column should previously have been defined as a Quantum column by means of the TableQuantumDesc object. In addition to the operations provided by its read-only partner, ROScalarQuantColumn , use of a ScalarQuantColumn object allows the insertion of Quanta into a column.
