trait ManyToMany[O, A] extends Query[O]
This trait is what is referred by both the left and right side of a manyToMany relation. Type parameters are : O: the type at the "other" side of the relation A: the association type i.e. the entity in the "middle" of the relation
Object mapping to the "middle" entity are called "association objects"
this trait extends Query[O] and can be queried against like a normal query.
Note that this trait is used on both "left" and "right" sides of the relation, but in a given relation

Abstract Value Members
- abstract def assign(o: O): A
Creates a new association object 'a' and calls assign(o,a)
- abstract def assign(o: O, a: A): A
- returns
the 'a' parameter is returned
- abstract def associate(o: O): A
Creates a new association object 'a' and calls associate(o,a)
Creates a new association object 'a' and calls associate(o,a)
Note that this method will fail if the association object has NOT NULL constraint fields apart from the foreign keys in the relations
- abstract def associate(o: O, a: A): A
- returns
the 'a' parameter is returned
- abstract def associationMap: Query[(O, A)]
- returns
a Query of Tuple2 containing all objects on the 'other side' along with their association object
- abstract def associations: Query[A]
a Query returning all of this member's association entries

- abstract def dissociate(o: O): Boolean
Causes the deletion of the 'Association object' between this side and the other side of the relation.
Causes the deletion of the 'Association object' between this side and the other side of the relation.
- returns
true if 'o' was associated (if an association object existed between 'this' and 'o') false otherwise
- abstract def dissociateAll: Int
Deletes all "associations" relating this "side" to the other
