Prerequisite

Etymology

The MSTable is the base class for all MeasurementSet Tables, hence the name.

Synopsis

A MSTable is a Table. Most operations on a MSTable are Table operations. See the Tables module for a list of those operations. The member functions provided by this class are primarily convenience functions to help users follow the agreed upon column and keyword naming conventions. They are useful when creating a Table following the MSTable conventions from scratch as well as when creating the column objects to access those columns. All actual MeasurementSet Tables will be derived from this class.

The standard way of accessing table columns is through Strings. Mistakes in typing the column name will not be caught at compile time (and may not be caught at run time). We have therefore decided to use an enumeration to specify columns so that many mistakes will be caught at compile time. This requires functions to map to and from this enumeration to the strings that are ultimately used.

Upon destruction, the table is checked to see that all required columns and keywords are still present. If not an exception is thrown. (Not a good idea!) Nevertheless, the table will be flushed to disk if it is writable - preserving its state.

Example

For examples of use, see the MeasurementSet class.

Motivation

The Table module is more than adequate as a container of data. However, in order for applications to be useful with data from different sources, some conventions need to be adopted in the use of Tables to store data. The MSTable provides the framework for these conventions and conversion functions. The actual definitions of columns and keywords are found in the derived classes and their "enum" base class (e.g. MSAntenna and MSAntennaEnums).

Member Function Documentation

template<class MSEnum>
static void casacore::MSTable< MSEnum >::addColumnCompression ( TableDesc td,
ColEnum  which,
Bool  autoScale = True,
const String type = String() 
)
static

Add the compress option for the given column to the TableDesc.

It can only be used for a Float or a Complex column. For complex columns the type determines which CompressComplex engine is used. "SD" means that CompressComplexSD is used; otherwise CompressComplex is used.

template<class MSEnum>
static void casacore::MSTable< MSEnum >::addColumnToDesc ( TableDesc tabDesc,
ColEnum  which,
Int  ndim = -1,
const String refCol = "" 
)
static

add a column to a TableDesc An exception is thrown for an invalid data type.

This indicates a programming error in this class when this occurs. For Array columns you can optionally define the dimension here. For Measure columns you can define a variable reference column.

Thrown Exceptions

template<class MSEnum>
static void casacore::MSTable< MSEnum >::addColumnToDesc ( TableDesc tabDesc,
ColEnum  which,
const IPosition shape,
ColumnDesc::Option  option,
