Method Details

getSingleValueHolder

public static @Nullable Object getSingleValueHolder(Object entity,
 String propertyName)

Returns a value holder of the given single-value reference attribute, woven into the entity class by the enhancing process.

Returns null if no value holder field is woven for the attribute, which means the attribute was not lazy at enhancing time (e.g. a @OneToOne(mappedBy = ...) attribute declared without fetch = FetchType.LAZY). Such attributes are always loaded eagerly by the ORM and do not participate in lazy loading.
