IDaoUpdateMultiAsync Method |
Async variant of
UpdateMulti(IEntity, ITransaction, IPredicate, IRelationCollection).
Updates all entities of the same type or subtype of the entity
entityWithNewValues directly in the persistent storage if they match the filter
supplied in
filterBucket. Only the fields changed in entityWithNewValues are updated for these fields. Entities of a subtype of the type
of
entityWithNewValues which are affected by the filterBucket's filter will thus also be updated.
