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).
To Do
-
referenceCopy() should be more flexible with the storage managers used for the columns which are not merely references.
-
When ForwardColumnEngine is fixed so that it can deal with tables already in the cache, modify the test program. It may also be necessary to modify referenceCopy().
