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. This is a specialization of Function for the case where the operand and result are of the same type.

    This interface is similar to UnaryOperator except that it is allowed to throw an IOException.

      • identity

        static <T> IOUnaryOperator<T> identity()
                                        throws java.io.IOException

        This method is the same as UnaryOperator.identity(), but with a support for IOException.

        Type Parameters:
        T - The type of the input and output of the operator.
        Returns:
        A unary operator that always returns its input argument.
        Throws:
        java.io.IOException - if there is an I/O error performing the operation.
