Interface DistributedUnaryOperator<T>

Type Parameters:

T - the type of the operand and result of the operator

All Superinterfaces:

DistributedFunction<T,T>, java.util.function.Function<T,T>, Serializable, java.util.function.UnaryOperator<T>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface DistributedUnaryOperator<T>
extends DistributedFunction<T,T>, java.util.function.UnaryOperator<T>, Serializable

Represents an operation on a single operand that produces a result of the same type as its operand. This is a specialization of Function for the case where the operand and result are of the same type.

This is a functional interface whose functional method is Function.apply(Object).
