java.lang.Object

org.springframework.data.history.Revisions<N,T>

All Implemented Interfaces:

Iterable<Revision<N,T>>, Supplier<Stream<Revision<N,T>>>, Streamable<Revision<N,T>>

public class Revisions<N extends Number & Comparable<N>,T>
extends Object
implements Streamable<Revision<N,T>>

Simple wrapper class for a List of Revisions allowing to canonically access the latest revision. Allows iterating over the underlying Revisions starting with older revisions.

of

public static <N extends Number & Comparable<N>,T> Revisions<N,T> of(List<? extends Revision<N,T>> revisions)

Creates a new Revisions instance for the given Revisions.

Returns:

will never be null.

none

public static <N extends Number & Comparable<N>,T> Revisions<N,T> none()

Creates a new empty Revisions instance.

Returns:

will never be null.

getLatestRevision

public Revision<N,T> getLatestRevision()

Returns the latest revision of the revisions backing the wrapper independently of the order.

Returns:

reverse
