Class JPAManyToManyProcessor
java.lang.Object
org.castor.jdo.jpa.processors.BaseJPAAnnotationProcessor
org.castor.jdo.jpa.processors.fieldprocessors.JPAManyToManyProcessor
- All Implemented Interfaces:
- AnnotationProcessor, TargetAwareAnnotationProcessor
public class JPAManyToManyProcessor
- extends BaseJPAAnnotationProcessor
Processes the JPA annotation ManyToMany
. This is the most complex
processor. After this processor is done, we know, that we have 2 fields that
have a well defined relation to each other. This processor checks for target
entities, relationship owning and checks that there is at least one join
definition for this relation.
After this processor is done, all 5 relation linked methods (and of cource
the Many2Many related ones) of JPAFieldNature
will return valid
values.

- the target (Field
, Class
, etc.) of the given
annotation
