Method Details

isFault

public boolean isFault()

Description copied from class: ToManyHolder

Returns whether this collection is not yet resolved and requires a fetch.

Specified by:

isFault in class ToManyHolder<E>

invalidate

public void invalidate()

Description copied from class: ToManyHolder

Turns this collection into a fault, thus forcing a refresh on the next access.

Specified by:

invalidate in class ToManyHolder<E>

resolveWith
