@Beta @CheckReturnValue public final class Funnels extends Object
Funnels for common types. All implementations are serializable.
Modifier and Type | Method and Description |
---|---|
static OutputStream |
asOutputStream(PrimitiveSink sink)
Wraps a
PrimitiveSink as an OutputStream , so it is easy to funnel an object to a PrimitiveSink if there is already a way to write the contents of the object to an OutputStream . |
static Funnel<byte[]> |
byteArrayFunnel()
Returns a funnel that extracts the bytes from a
byte array. |
static Funnel<Integer> |
integerFunnel()
Returns a funnel for integers.
|
static Funnel<Long> |
longFunnel()
Returns a funnel for longs.
|
static <E> Funnel<Iterable<? extends E>> |
sequentialFunnel(Funnel<E> elementFunnel)
Returns a funnel that processes an
Iterable by funneling its elements in iteration order with the specified funnel. |
static Funnel<CharSequence> |
stringFunnel(Charset charset)
Returns a funnel that encodes the characters of a
CharSequence with the specified Charset . |
static Funnel<CharSequence> |
unencodedCharsFunnel()
Returns a funnel that extracts the characters from a
CharSequence , a character at a time, without performing any encoding. |
public static Funnel<byte[]> byteArrayFunnel()
Returns a funnel that extracts the bytes from a byte
array.
public static Funnel<CharSequence> unencodedCharsFunnel()
Returns a funnel that extracts the characters from a CharSequence
, a character at a time, without performing any encoding. If you need to use a specific encoding, use stringFunnel(Charset)
instead.
Funnels.stringFunnel()
.public static Funnel<CharSequence> stringFunnel(Charset charset)
Returns a funnel that encodes the characters of a CharSequence
with the specified Charset
.
public static Funnel<Integer> integerFunnel()
Returns a funnel for integers.
public static <E> Funnel<Iterable<? extends E>> sequentialFunnel(Funnel<E> elementFunnel)
Returns a funnel that processes an Iterable
by funneling its elements in iteration order with the specified funnel. No separators are added between the elements.
public static OutputStream asOutputStream(PrimitiveSink sink)
Wraps a PrimitiveSink
as an OutputStream
, so it is easy to funnel
an object to a PrimitiveSink
if there is already a way to write the contents of the object to an OutputStream
.
The close
and flush
methods of the returned OutputStream
do nothing, and no method throws IOException
.
