This is the Hibernate Validator API documentation. Hibernate Validator is the reference implementation of
 Bean Validation 1.1 - JSR-349
All classes fall into three categories:
    - spi: Classes with spi in the package name are service provider interfaces intended to be implemented
        or extended by users of Hibernate Validator.
    
- internal: Classes with internal in the package name are Hibernate Validator specific classes which are
        not intended for use. Internal classes can change at any time and no guarantee is given regarding backwards
        compatibility.
    
- public: Classes with neither spi or internal in the package name are considered public and can be used or
        extended by users. If changes to this classes are necessary there will be a deprecation first.
