Examples of AssociationKey

org.hibernate.engine.spi.AssociationKey
Identifies a named association belonging to a particular entity instance. Used to record the fact that an association is null during loading. @author Gavin King
org.hibernate.ogm.grid.AssociationKey
Represents the key used to link a property value and the id of it's owning entity @author Emmanuel Bernard @author Sanne Grinovero @author Gunnar Morling

Represents the key used to link a property value and the id of it's owning entity @author Emmanuel Bernard @author Sanne Grinovero @author Gunnar Morling
org.hibernate.persister.walking.spi.AssociationKey
Used to uniquely identify a foreign key, so that we don't join it more than once creating circularities. Note that the table+columns refers to the association owner. These are used to help detect bi-directional associations since the Hibernate runtime metamodel (persisters) do not inherently know this information. For example, consider the Order -> Customer and Customer -> Order(s) bi-directional association; both would be mapped to the {@code ORDER_TABLE.CUST_ID} column. That is the purpose of this struct.
Bit of a misnomer to call this an association attribute. But this follows the legacy use of AssociationKey from old JoinWalkers to denote circular join detection @author Steve Ebersole @author Gail Badner @author Gavin King
