ch.tocco.nice2.optional.address.impl.merge.AbstractAddressAddressAndUserUserRelationMergeHandler

All Implemented Interfaces:

RelationMergeHandler

Direct Known Subclasses:

AddressAddressRelationMergeHandler, UserUserRelationMergeHandler

public abstract class AbstractAddressAddressAndUserUserRelationMergeHandler
extends ToManyRelationMergeHandler

Abstract RelationMergeHandler for Address->Address_address and User->User_user relations. This handler removes potential duplicates if multiple source entities have a relation to the same entity. This is necessary to avoid a validation error. If there are duplicates it is important to remove the 'new' value and keep the existing one, because the validator uses a query to compare uniqueness.
