- - antlr.LLkParser
  - - org.hibernate.hql.internal.antlr.HqlBaseParser
    - - org.hibernate.hql.internal.ast.HqlParser

所有已实现的接口:

HqlTokenTypes
```
public final class HqlParser
extends HqlBaseParser
```
Implements the semantic action methods defined in the HQL base parser to keep the grammar source file a little cleaner. Extends the parser class generated by ANTLR.
