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.
