org.hibernate.hql.antlr
Class HqlSqlBaseWalker

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

All Implemented Interfaces:

HqlSqlTokenTypes

Direct Known Subclasses:

HqlSqlWalker

public class HqlSqlBaseWalker
extends antlr.TreeParser
implements HqlSqlTokenTypes

Hibernate Query Language to SQL Tree Transform.
This is a tree grammar that transforms an HQL AST into a intermediate SQL AST with bindings to Hibernate interfaces (Queryable, etc.). The Hibernate specific methods are all implemented in the HqlSqlWalker subclass, allowing the ANTLR-generated class to have only the minimum dependencies on the Hibernate code base. This will also allow the sub-class to be easily edited using an IDE (most IDE's don't support ANTLR).
NOTE: The java class is generated from hql-sql.g by ANTLR. DO NOT EDIT THE GENERATED JAVA SOURCE CODE.
