Interface IOUnaryOperator<T>

  • Type Parameters:
    T - the type of the operand and result of the operator
    All Superinterfaces:
    IOFunction<T,​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 IOUnaryOperator<T>
    extends IOFunction<T,​T>
    Represents an operation on a single operand that produces a result of the same type as its operand.
