Class: TeraWurflMySQLNestedSet

Source Location: /DatabaseConnectors/TeraWurflMySQLNestedSet.php

Class Overview

Takes an existing table with data in ancestor..descendent hierarchial format and ALTERs the table by adding a right and left (`rt` and `lt`) columns. These columns contain the nested set relationships between the nodes. This makes certain lookups (like fallback trees) extremely simple and very fast.
