Prerequisite

TableExprNodeMulti

Etymology

TableExprNodeIndex is used to store an index. All the operands must be Int.

Synopsis

TableExprNodeIndex is a derivation of TableExprNodeMulti expression tree that represents an index.

Motivation

All operands of TableExprNodeIndex must be Int, therefore it is a derivation of TableExprNodeMulti.

To Do
