Class FrozenCollectionRows

java.lang.Object

org.hibernate.collection.spi.FrozenCollectionRows

@Incubating(since="8.0",
            group="collection-delta")
public final class FrozenCollectionRows
extends Object

A validity-guarded projection of the current rows of a persistent collection.

The projection uses immutable segmented parallel arrays instead of allocating a second object for every collection row. Segments let production retain a single pass over the live collection without repeatedly copying a growing array. It retains the collection comparison generation and enumerates each included row directly into the physical consumer. Access fails if the collection changes after the projection is created.
