@FunctionalInterface public static interface Remote.IntBinaryOperator extends IntBinaryOperator, Serializable
int-valued operands and
 producing an int-valued result.   This is the primitive type
 specialization of BinaryOperator for int.
 
This is a functional interface
 whose functional method is IntBinaryOperator.applyAsInt(int, int).
