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
    See Also:
    IOBiFunction, BinaryOperator

    • Method Detail

      • 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:
        java.lang.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:
        java.lang.NullPointerException - if the argument is null

      • asBinaryOperator

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