// StManColumn handles a column for a storage manager.
// </etymology>

// <synopsis> 
// StManColumn is the abstract base class to handle a column in all
// kind of storage managers. It is derived from DataManagerColumn
// and implements several virtual functions for derived storage
// manager column classes (like StManColumnAipsIO).
//
// All get and put functions (except for single scalars) in the abstract
// base class DataManagerColumn have a generic void* data argument.
// This is done to allow arbitrary typed arguments. This can be done
// because the data type of the derived class always matches the
// type of the data argument.
// However, at one time the void* has to be casted to the exact type.
// Storage managers only support the standard data types; therefore
// it is possible to do the cast in a base class. This concentrates
// the burden in one class and allows the derived classes to work
// with correctly typed arguments.
// The price is an extra virtual function call, but that is not a
// problem for (expensive) operations on arrays.
// It is not done for single scalars, because that price may be too high.
// 
// See StManColumnAipsIO for the get/put functions required in a storage
// manager column class handling scalars.
// See StManColumnArrayAipsIO for the get/put functions required in a
// storage manager column class handling arrays. This class also
// contains the shape functions for direct arrays, while
// StManColumnIndArrayAipsIO contains the shape functions for indirec
// arrays.
//
// StManColumn also contains the data type of the column (which it
// gets from the derived classes at construction time) and implements
// the function dataType on behalf of its derived classes.
// </synopsis> 

// <motivation>
// Making life easier for the derived classes.
