## Hibernate API

This documentation concentrates upon the following Core API interfaces:
- `org.hibernate.Hibernate`
- `org.hibernate.Session`
- `org.hibernate.SessionFactory`
- `org.hibernate.Transaction`
- `org.hibernate.Query`
- `org.hibernate.Criteria`
- `org.hibernate.ScrollableResults`
- `org.hibernate.cfg.Configuration`
- `org.hibernate.expression.Expression`
- `org.hibernate.expression.Order`
- `org.hibernate.expression.Example`
These interfaces are fully intended to be exposed to application code.
The Extension API is intended to be used by application programmers to extend Hibernate functionality. None of these interfaces are intended to be called by the application - they are called internally by Hibernate. This API is less stable than the Core API. The safest way to extend functionality is to contribute extensions back to the project; that way extensions will be updated when the Extension API changes.
