    - #### Pipe

          public Pipe(org.apache.http.nio.IOControl producerIoControl,
                      ControlledByteBuffer buffer,
                      String name,
                      BaseConfiguration baseConfig)

    - #### Pipe

          public Pipe(ControlledByteBuffer buffer,
                      String name,
                      BaseConfiguration baseConfig)

  - ### Method Detail

    - #### isProducerCompleted

          public boolean isProducerCompleted()

    - #### attachConsumer

          public void attachConsumer(org.apache.http.nio.IOControl consumerIoControl)

      Set the consumers IOControl
      Parameters:
        `consumerIoControl` - IOControl of the consumer

    - #### consume

          public int consume(org.apache.http.nio.ContentEncoder encoder)
                      throws IOException

      Consume the data from the buffer. Before calling this method attachConsumer method must be called with a valid IOControl.
      Parameters:
        `encoder` - encoder used to write the data means there will not be any data written in to this buffer
      Returns:
        number of bytes written (consumed)
      Throws:
        `IOException` - if an error occurred while consuming data

    - #### produce

          public int produce(org.apache.http.nio.ContentDecoder decoder)
                      throws IOException

      Produce data in to the buffer.
      Parameters:
        `decoder` - decoder to read bytes from the underlying stream
      Returns:
        bytes read (consumed)
      Throws:
        `IOException` - if an error occurs while reading data

    - #### forceProducerComplete

          public void forceProducerComplete(org.apache.http.nio.ContentDecoder decoder)

      Helper method to mark as producer completed. The normal behavior only set the boolean param to true only when decoder is completed. However in some cases it is needed to intentionally close chunk stream and mark as producer completed in order to prevent consumer further waiting on end of stream condition.
      Parameters:
        `decoder` - decoder instance to consume input

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `Object`

    - #### consumerError

          public void consumerError()

    - #### producerError

          public void producerError()

    - #### getInputStream

          public InputStream getInputStream()

      Creates an InputStream object on the underlying ByteBuffer. The returned InputStream can be used to read bytes from the underlying buffer which is being filled by the producer.
      Returns:
        An InputStream object

    - #### getOutputStream

          public OutputStream getOutputStream()

      Creates a separate ByteBuffer for the output data and returns an OutputStream on top of it.
      Returns:
        An OutputStream object

    - #### resetOutputStream

          public OutputStream resetOutputStream()

      Creates a separate ByteBuffer for the output data and returns an OutputStream on top of it.
      Returns:
        An OutputStream object

    - #### setSerializationComplete

          public void setSerializationComplete(boolean serializationComplete)

    - #### setSerializationCompleteWithoutData

          public void setSerializationCompleteWithoutData(boolean serializationComplete)

    - #### setRawSerializationComplete

          public void setRawSerializationComplete(boolean rawSerializationComplete)

    - #### forceSetSerializationRest

          public void forceSetSerializationRest()

    - #### isSerializationComplete

          public boolean isSerializationComplete()

    - #### getBuffer

          public ControlledByteBuffer getBuffer()

    - #### hasHttpProducer

          public boolean hasHttpProducer()

    - #### isConsumeRequired

          public boolean isConsumeRequired()
                                    throws IOException

      This method returns whether buffer consumption is required or not.
      Returns:
        boolean
      Throws:
        `IOException`
