## Interface IOBinaryOperator<T>

- Type Parameters:
    `T` - the type of the operands and result of the operator.
  All Superinterfaces:
    IOBiFunction<T,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 IOBinaryOperator<T>
      extends IOBiFunction<T,T,T>

  Like `BinaryOperator` but throws `IOException`.
  See Also:
    `IOBiFunction`, `BinaryOperator`

    `default java.util.function.BinaryOperator<T>` | `asBinaryOperator()` Creates a `BinaryOperator` for this instance that throws `UncheckedIOException` instead of `IOException`.
    `static <T> IOBinaryOperator<T>` | `maxBy(IOComparator<? super T> comparator)` Creates a `IOBinaryOperator` which returns the greater of two elements according to the specified `Comparator`.
    `static <T> IOBinaryOperator<T>` | `minBy(IOComparator<? super T> comparator)` Creates a `IOBinaryOperator` which returns the lesser of two elements according to the specified `Comparator`.

    - #### asBinaryOperator

          default java.util.function.BinaryOperator<T> asBinaryOperator()

      Creates a `BinaryOperator` for this instance that throws `UncheckedIOException` instead of `IOException`.
      Returns:
        an unchecked BiFunction.

    - #### maxBy

          static <T> IOBinaryOperator<T> maxBy(IOComparator<? super T> comparator)

      Creates a `IOBinaryOperator` which returns the greater of two elements according to the specified `Comparator`.
      Type Parameters:
        `T` - the type of the input arguments of the comparator
      Parameters:
        `comparator` - a `Comparator` for comparing the two values
      Returns:
        a `BinaryOperator` which returns the greater of its operands, according to the supplied `Comparator`
      Throws:
        `NullPointerException` - if the argument is null

    - #### minBy

          static <T> IOBinaryOperator<T> minBy(IOComparator<? super T> comparator)

      Creates a `IOBinaryOperator` which returns the lesser of two elements according to the specified `Comparator`.
      Type Parameters:
        `T` - the type of the input arguments of the comparator
      Parameters:
        `comparator` - a `Comparator` for comparing the two values
      Returns:
        a `BinaryOperator` which returns the lesser of its operands, according to the supplied `Comparator`
      Throws:
        `NullPointerException` - if the argument is null
