Etymology
TabVecRep is the representation of a table vector.
Synopsis
TabVecRep is the counted referenced letter class for the envelope class TableVector. It is an abstract base class for the actual table vector classes TabVecScaCol and TabVecTemp.
All operations defined for TableVector are immediately passed to the corresponding virtual TabVecRep function. The header files TVecMath.h and TVecLogic.h declare all the mathematical and logical functions for TabVecRep.
Motivation
A virtual function call only works when used with an object pointer or reference. To allow the use of virtual functions in value objects, an extra level of indirection is used. This is called the letter/envelope idiom and is described in "Advanced C++" by J. Coplien. Class TableVector is the envelope to the letters TabVecRep and its derivations.
To Do
-
put the TabVecTag enum inside the class definition
-
support array columns
