Method Details

clearInitialValues

public void clearInitialValues(Object entity)

Sets to null, directly in the fields, the values assigned when the instance was created, so that a later set of any value fires a change event and marks the attribute loaded.

Keeps the primary key, JmixGeneratedValue values (equals() and hashCode() can depend on them), embedded instances and element collections (entity code can expect them to be not null).
