All Implemented Interfaces:

CommandRenderer, DateRenderer, QueryRenderer

public class DelegatedSQLRenderEngine
extends java.lang.Object
implements QueryRenderer, CommandRenderer, DateRenderer

A SQL rendering engine that provides for a delegate, and passes through all rendering requests to that delegate. It's for extensibility. TODO: Evaluate the elimination of the DatabaseType enum (at least as TODO: a vendor construct) and eliminate the need for this indirection.
