org.hibernate.hql.internal.ast
Class SqlGenerator

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