Prerequisite
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:
- 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.
- 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.
