Interface ThrowingUnaryOperator<T,​X extends Exception>

  • Type Parameters:
    T - the type of the operand and result of the operator
    X - the type of the exception that might be thrown
    All Superinterfaces:
    ThrowingFunction<T,​T,​X>
    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 ThrowingUnaryOperator<T,​X extends Exception>
    extends ThrowingFunction<T,​T,​X>
    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.
