      All Methods Static Methods Concrete Methods 
      Modifier and Type Method Description
      static asOutputStream​(PrimitiveSink sink)
      Wraps a PrimitiveSink as an , 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 > integerFunnel()
      Returns a funnel for integers.
      static > longFunnel()
      Returns a funnel for longs.
      static <E> <? 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 >  charset)
      Returns a funnel that encodes the characters of a CharSequence with the specified Charset.
      static > 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 > 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.

      • stringFunnel

        public static >  charset)
        Returns a funnel that encodes the characters of a CharSequence with the specified Charset.

      • integerFunnel

        public static > integerFunnel()
        Returns a funnel for integers.

      • sequentialFunnel

        public static <E> <? 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.

      • longFunnel

        public static > longFunnel()
        Returns a funnel for longs.
        Since:

      • asOutputStream

        public static  asOutputStream​(PrimitiveSink sink)
        Wraps a PrimitiveSink as an , 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.
