## org.hibernate.hql.ast
Class SqlGenerator

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

All Implemented Interfaces:
  SqlTokenTypes, ErrorReporter

    public class SqlGenerator

extends SqlGeneratorBase
implements ErrorReporter

Generates SQL by overriding callback methods in the base class, which does the actual SQL AST walking.
