Method Summary
All Methods Static Methods Concrete Methods Modifier and Type Method Description static OutputStream
asOutputStream(PrimitiveSink sink)
Wraps aPrimitiveSink
as anOutputStream
, so it is easy tofunnel
an object to aPrimitiveSink
if there is already a way to write the contents of the object to anOutputStream

Funnel<Iterable<? extends E>>sequentialFunnel(Funnel<E> elementFunnel)
Returns a funnel that processes anIterable
by funneling its elements in iteration order with the specified funnel.static Funnel<CharSequence>

Returns a funnel that encodes the characters of aCharSequence
with the specifiedCharset

Method Detail
-
byteArrayFunnel
public static Funnel<byte[]> byteArrayFunnel()
Returns a funnel that extracts the bytes from abyte
array.
-
unencodedCharsFunnel
public static Funnel<CharSequence> unencodedCharsFunnel()
Returns a funnel that extracts the characters from aCharSequence
, a character at a time, without performing any encoding. If you need to use a specific encoding, usestringFunnel(Charset)
instead.- Since:
- 15.0 (since 11.0 as
Funnels.stringFunnel()
.
-
stringFunnel
public static Funnel<CharSequence> stringFunnel(Charset charset)
Returns a funnel that encodes the characters of aCharSequence
with the specifiedCharset
.- Since:
- 15.0
-
integerFunnel
public static Funnel<Integer> integerFunnel()
Returns a funnel for integers.- Since:
- 13.0
-
sequentialFunnel
public static <E extends @Nullable Object> Funnel<Iterable<? extends E>> sequentialFunnel(Funnel<E> elementFunnel)
Returns a funnel that processes anIterable
by funneling its elements in iteration order with the specified funnel. No separators are added between the elements.- Since:
- 15.0
-
longFunnel
public static Funnel<Long> longFunnel()
Returns a funnel for longs.- Since:
- 13.0
-
asOutputStream
public static OutputStream asOutputStream(PrimitiveSink sink)
Wraps aPrimitiveSink
as anOutputStream
, so it is easy tofunnel
an object to aPrimitiveSink
if there is already a way to write the contents of the object to anOutputStream
.The
close
andflush
methods of the returnedOutputStream
do nothing, and no method throwsIOException
.- Since:
- 13.0
