shouldDelegateOnRecursiveLoad

protected boolean shouldDelegateOnRecursiveLoad()

Description copied from class: AbstractValueHolder

Allows a reentrant AbstractValueHolder.getValue() call, made while this holder is already loading, to delegate to the original EclipseLink holder instead of starting the same Jmix load again.

Keep this opt-in: it is needed for collection holders whose owner is managed. During the internal owner reload, EclipseLink may resolve the same owner instance from the persistence context and touch the same collection holder. For detached owners the reload uses another managed instance, so the original holder is not expected to re-enter.

Overrides:

shouldDelegateOnRecursiveLoad in class AbstractValueHolder

Returns:

true only when delegating is needed to break same-holder recursion

loadValue

protected Object loadValue()

Specified by:

loadValue in class AbstractValueHolder

afterLoadValue

protected void afterLoadValue(Object value)

Specified by:

afterLoadValue in class AbstractValueHolder

createLoadContextByOwner

protected LoadContext<?> createLoadContextByOwner(MetaClass metaClass)

replaceCollectionExistingReferences

protected void replaceCollectionExistingReferences(Collection<Object> collection,
 Object entityToReplace)
