Detailed Description

The index of an array element in a table select expression.

Intended use:

Internal

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

• to be filled in
