public class JPAManyToManyProcessor extends BaseJPAAnnotationProcessor
Processes the JPA annotationManyToMany
. 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) ofJPAFieldNature
will return valid values.- Version:
