Method Summary

Modifier and Type	Method	Description
static <V> void	forEachIo(Stream<V> stream, Consumer<V> cons)	Executes a Stream.forEach(Consumer) on a stream that uses IO-versions of lambdas and spits out any thrown IOException
static <T,R> Function<T,R>	iof(IOUtils.IOFunction<T,R> fun)	Wraps provided Function into an IOFunction.
static <V> Stream<V>	ioOptStream(IOUtils.IOSupplier<V> supp)	Creates a stream from a single element returned by provided IOSupplier.
static <T> Predicate<T>	iop(IOUtils.IOPredicate<T> pred)	Wraps provided Predicate into an IOPredicate.
static void	withIo(Runnable run)	Executes a terminal operation that uses IO-versions of lambdas and spits out any thrown IOException
static <V> V	withIo(Supplier<V> supp)	Executes a terminal operation that uses IO-versions of lambdas and spits out any thrown IOException

Method Detail

iof

public static <T,R> Function<T,R> iof(IOUtils.IOFunction<T,R> fun)

Wraps provided Function into an IOFunction. Users are expected to wrap stream terminal operations using withIo(Runnable) or withIo(Supplier)

iop

public static <T> Predicate<T> iop(IOUtils.IOPredicate<T> pred)

Wraps provided Predicate into an IOPredicate. Users are expected to wrap stream terminal operations using withIo(Runnable) or withIo(Supplier)

withIo

public static <V> V withIo(Supplier<V> supp)
                    throws IOException

Executes a terminal operation that uses IO-versions of lambdas and spits out any thrown IOException

Throws:

IOException

withIo

public static void withIo(Runnable run)
                   throws IOException

Executes a terminal operation that uses IO-versions of lambdas and spits out any thrown IOException

Throws:

IOException

forEachIo

public static <V> void forEachIo(Stream<V> stream,
                                 Consumer<V> cons)
                          throws IOException

Executes a Stream.forEach(Consumer) on a stream that uses IO-versions of lambdas and spits out any thrown IOException

Throws:

IOException

ioOptStream

public static <V> Stream<V> ioOptStream(IOUtils.IOSupplier<V> supp)

Creates a stream from a single element returned by provided IOSupplier. If supplier throws an IOException, returns Stream.empty()
