Method Summary

Modifier and Type	Method and Description
static java.io.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<HashCode>	hashCodeFunnel() Returns a funnel for hashcode.
static Funnel<java.lang.Integer>	integerFunnel() Returns a funnel for integers.
static Funnel<java.lang.Long>	longFunnel() Returns a funnel for longs.
static <E> Funnel<java.lang.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<java.lang.CharSequence>	stringFunnel(java.nio.charset.Charset charset) Returns a funnel that encodes the characters of a CharSequence with the specified Charset.
static Funnel<java.lang.CharSequence>	unencodedCharsFunnel() Returns a funnel that extracts the characters from a CharSequence, a character at a time, without performing any encoding.

Method Detail

byteArrayFunnel

public static Funnel<byte[]> byteArrayFunnel()

Returns a funnel that extracts the bytes from a byte array.

unencodedCharsFunnel

public static Funnel<java.lang.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.

Since:

15.0 (since 11.0 as Funnels.stringFunnel().

stringFunnel

public static Funnel<java.lang.CharSequence> stringFunnel(java.nio.charset.Charset charset)

Returns a funnel that encodes the characters of a CharSequence with the specified Charset.

Since:

15.0

integerFunnel

public static Funnel<java.lang.Integer> integerFunnel()

Returns a funnel for integers.

Since:

13.0

sequentialFunnel

public static <E> Funnel<java.lang.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.

Since:

15.0

longFunnel

public static Funnel<java.lang.Long> longFunnel()

Returns a funnel for longs.

Since:

13.0

asOutputStream

public static java.io.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.

Since:

13.0

hashCodeFunnel

public static Funnel<HashCode> hashCodeFunnel()

Returns a funnel for hashcode.
