Interface Ordering.Serial<E>

All Superinterfaces:

Ordering<E>, java.io.Serializable

Enclosing interface:

Ordering<T>

public static interface Ordering.Serial<E>
extends Ordering<E>, java.io.Serializable

An 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 (Ordering<T> & Serializable) (v1, v2) -> v1.compareTo(v2);
 

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