Method Summary

Methods
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.

  - byteArrayFunnel
```
public static Funnel<byte[]> byteArrayFunnel()
```
    Returns a funnel that extracts the bytes from a byte array.
  - unencodedCharsFunnel
```
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.

    15.0 (since 11.0 as Funnels.stringFunnel().
  - stringFunnel
```
public static Funnel<CharSequence> stringFunnel(Charset charset)
```
    Returns a funnel that encodes the characters of a CharSequence with the specified Charset.

    15.0
  - integerFunnel
```
public static Funnel<Integer> integerFunnel()
```
    Returns a funnel for integers.

  - sequentialFunnel
```
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.
    
    Since:
    
    15.0
  - longFunnel
```
public static Funnel<Long> longFunnel()
```
    Returns a funnel for longs.
    
    Since:

  - asOutputStream
```
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.
