Detailed Description

Class to visit the nodes in the raw TaQL parse tree.

Intended use:

Internal

Review Status

Test programs:
tTableGram

Prerequisite

Synopsis

TaQLNodeVisitor is the abstract base class for classes that want to visit a TaQLNode tree, i.e. traverse the tree. Each visit results in a TaQLNodeResult object which acts as the basis for the actual result object.
A specialization of TaQLNodeVisitor (e.g. class TaQLNodeHandler needs to implement the various visitXXNode functions. A visit function will process a node which usually means visiting its children, etc..

Motivation

The visitor design pattern separates the tree from the way it is processed. In this way any handler can be created. For instance, a query optimizer could be a future other handler.
