Method Detail

intKeyOrdering

public static <K extends com.google.gwtorm.client.IntKey<?>> com.google.common.collect.Ordering<K> intKeyOrdering()

Null-safe ordering over arbitrary subclass of IntKey.

In some cases, Comparator.comparing(Change.Id::get) may be shorter and cleaner. However, this method may be preferable in some cases:

• This ordering is null-safe over both input and the result of IntKey.get(); comparing is only a good idea if all inputs are obviously non-null.
• intKeyOrdering().sortedCopy(iterable) is shorter than the stream equivalent.
• Creating derived comparators may be more readable with Ordering method chaining rather than static Comparator methods.
