Package org.apache.commons.io.function

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.
Since:
2.12.0

    • 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

    • asBinaryOperator

      default BinaryOperator<T> asBinaryOperator()
      Creates a BinaryOperator for this instance that throws UncheckedIOException instead of IOException.
      Returns:
      an unchecked BiFunction.
