<para>JPA 2 defines a new typesafe <classname>Criteria</classname> API
|

which allows criteria queries to be constructed in a strongly-typed
|
||||
manner, using metamodel objects to provide type safety. This type saftey
|
||||
is of course only useful for developers if the task of the metamodel
|
||||
generation can be automated. Hibernate Static Metamodel Generator is an
|
||||
annotation processor based on the annotation processing API defined in
|
||||
<ulink url="???">JSR 269</ulink> with the task of creating the static
|
||||
metamodel classes for JPA 2 entities. The following examples show a

managed JPA 2 entity, together with is metamodel class and an example

typesafe query.</para>
