Prerequisite

• TabVecRep

Etymology

TabVecTemp is the class dealing with a table vector when used as a temporary in math operations.

Synopsis

TabVecTemp objects enable the use of Vector objects as table vectors. They are used for 2 purposes:

1. To convert a Vector to a TableVector. This is used to allow the use of Vectors in TableVector expressions. The TabVecTemp object uses the Vector copy constructor, which is very cheap due to its reference semantics.
2. To hold the result of an operation (like addition) on two TableVector objects.

Motivation

TabVecTemp is derived from TabVecRep and as such a letter for the envelope class TableVector.

Template Type Argument Requirements (T)

• Default constructor
• Copy constructor
• Assignment operator

To Do

• In the future temporary results may need to use a file, because table vectors can potentially be very, very long.
