All Implemented Interfaces:

GeneratedOrderByFragmentRendererTokenTypes

public class OrderByFragmentRenderer
extends GeneratedOrderByFragmentRenderer

Extension of the Antlr-generated tree walker for rendering the parsed order-by tree back to String form. out(antlr.collections.AST) is the sole semantic action here and it is used to utilize our split between text (tree debugging text) and "renderable text" (text to use during rendering).
