Method Detail

none

public static Predicate<ChangeData> none()

Returns an index predicate that matches no changes in the index.

This predicate should be used in preference to a non-index predicate (such as Predicate.not(Predicate.any())), since it can be matched efficiently against the index.

Returns:

an index predicate matching no changes.
