getUpdatedNotRemoved

public Stream<V> getUpdatedNotRemoved(ModelCriteriaBuilder<M> mcb)

Returns the stream of records that match given criteria and includes changes made in this transaction, i.e. the result contains updates and excludes records that have been deleted in this transaction.

Parameters:

mcb -

Returns:

getCount

public long getCount(ModelCriteriaBuilder<M> mcb)

Returns the stream of records that match given criteria and includes changes made in this transaction, i.e. the result contains updates and excludes records that have been deleted in this transaction.

Parameters:

Parameters:

orig -

The orig object as visible from this transaction, or null if the object has been removed.

update

public void update(K key,
                   V value)

create

public void create(K key,
                   V value)

updateIfChanged

public void updateIfChanged(K key,
                            V value,
                            Predicate<V> shouldPut)
