Interface IntOrdering.Serial

All Superinterfaces:

ByteOrdering, CharOrdering, IntOrdering, java.io.Serializable, ShortOrdering

Enclosing interface:

IntOrdering

public static interface IntOrdering.Serial
extends IntOrdering, java.io.Serializable

An int ordering which is serializable. It is a recommendation that comparators implement java.io.Serializable to allow serializing TreeMaps and similar. If an Ordering is expected to be used as a comparator in such areas implement either this interface, or for lambdas use a cast to force the compiler to make the order serializable:

   return (IntOrdering & Serializable) (v1, v2) -> v1.compareTo(v2);
 

You can also use a (IntOrdering.Serial) cast to save a bit of typing, but the above is a nice trick to have in your toolbox.
