Methods in org.apache.commons.io.function that return IOFunction

Modifier and Type	Method	Description
default <V> IOFunction<T,V>	IOFunction.andThen(Function<? super R,? extends V> after)	Returns a composed IOFunction that first applies this function to its input, and then applies the after function to the result.
default <V> IOFunction<T,V>	IOFunction.andThen(IOFunction<? super R,? extends V> after)	Returns a composed IOFunction that first applies this function to its input, and then applies the after function to the result.
default <V> IOFunction<V,R>	IOFunction.compose(Function<? super V,? extends T> before)	Returns a composed IOFunction that first applies the before function to its input, and then applies this function to the result.
default <V> IOFunction<V,R>	IOFunction.compose(IOFunction<? super V,? extends T> before)	Returns a composed IOFunction that first applies the before function to its input, and then applies this function to the result.
static <T> IOFunction<T,T>	IOFunction.identity()	Returns a IOFunction that always returns its input argument.

Methods in org.apache.commons.io.function with parameters of type IOFunction

Modifier and Type	Method	Description
default <V> IOBiFunction<T,U,V>	IOBiFunction.andThen(IOFunction<? super R,? extends V> after)	Creates a composed function that first applies this function to its input, and then applies the after function to the result.
default <V> IOFunction<T,V>	IOFunction.andThen(IOFunction<? super R,? extends V> after)	Returns a composed IOFunction that first applies this function to its input, and then applies the after function to the result.
default <X> IOQuadFunction<T,U,V,W,X>	IOQuadFunction.andThen(IOFunction<? super R,? extends X> after)	Creates a composed function that first applies this function to its input, and then applies the after function to the result.
default <W> IOTriFunction<T,U,V,W>	IOTriFunction.andThen(IOFunction<? super R,? extends W> after)	Creates a composed function that first applies this function to its input, and then applies the after function to the result.
static <T, R> R	Uncheck.apply(IOFunction<T,R> function, T t)	Applies an IO function with the given arguments.
default <V> IOFunction<V,R>	IOFunction.compose(IOFunction<? super V,? extends T> before)	Returns a composed IOFunction that first applies the before function to its input, and then applies this function to the result.
default <R> IOStream<R>	IOStream.flatMap(IOFunction<? super T,? extends IOStream<? extends R>> mapper)	Like Stream.flatMap(java.util.function.Function).
default DoubleStream	IOStream.flatMapToDouble(IOFunction<? super T,? extends DoubleStream> mapper)	TODO Package-private for now, needs IODoubleStream? Adding this method now and an IO version later is an issue because call sites would have to type-cast to pick one.
default IntStream	IOStream.flatMapToInt(IOFunction<? super T,? extends IntStream> mapper)	TODO Package-private for now, needs IOIntStream? Adding this method now and an IO version later is an issue because call sites would have to type-cast to pick one.
default LongStream	IOStream.flatMapToLong(IOFunction<? super T,? extends LongStream> mapper)	TODO Package-private for now, needs IOLongStream? Adding this method now and an IO version later is an issue because call sites would have to type-cast to pick one.
default <R> IOStream<R>	IOStream.map(IOFunction<? super T,? extends R> mapper)	Like Stream.map(java.util.function.Function).
