org.hibernate.hql.antlr
Class SqlGeneratorBase

java.lang.Object
  antlr.TreeParser
      org.hibernate.hql.antlr.SqlGeneratorBase

All Implemented Interfaces:: SqlTokenTypes

Direct Known Subclasses:: SqlGenerator

public class SqlGeneratorBase
extends antlr.TreeParser
implements SqlTokenTypes

SQL Generator Tree Parser, providing SQL rendering of SQL ASTs produced by the previous phase, HqlSqlWalker. All syntax decoration such as extra spaces, lack of spaces, extra parens, etc. should be added by this class.
This grammar processes the HQL/SQL AST and produces an SQL string. The intent is to move dialect-specific code into a sub-class that will override some of the methods, just like the other two grammars in this system.
