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>
LikeBinaryOperator
but throwsIOException
.- Since:
- 2.12.0

comparator
- aComparator
for comparing the two values- Returns:
- a
BinaryOperator
which returns the greater of its operands, according to the suppliedComparator
- Throws:
java.lang.NullPointerException
- if the argument is null
-
minBy
static <T> IOBinaryOperator<T> minBy(IOComparator<? super T> comparator)
Creates aIOBinaryOperator
which returns the lesser of two elements according to the specifiedComparator
.- Type Parameters:
T
- the type of the input arguments of the comparator- Parameters:
comparator
- aComparator
for comparing the two values- Returns:
- a
BinaryOperator
which returns the lesser of its operands, according to the suppliedComparator
- Throws:
java.lang.NullPointerException
- if the argument is null
-
asBinaryOperator
default java.util.function.BinaryOperator<T> asBinaryOperator()
Creates aBinaryOperator
for this instance that throwsUncheckedIOException
instead ofIOException
.- Returns:
- an unchecked BiFunction.
