Method Detail

• doRead

  int doRead(ByteChunk chunk,
           Request request)
             throws IOException

  Read from the input stream into the given buffer. IMPORTANT: the current model assumes that the protocol will 'own' the buffer and return a pointer to it in ByteChunk (i.e. the param will have chunk.getBytes()==null before call, and the result after the call).

  Parameters:

  chunk - The buffer to read data into.

  request - The associated request

  Returns:

  The number of bytes that have been added to the buffer or -1 for end of stream

  Throws:

  IOException - If an I/O error occurs reading from the input stream

• available

  int available()

  Obtain an estimate of the number of bytes that can be read without blocking. Typically, this will be the number of available bytes known to be buffered.

  Returns:

  The number of bytes that can be read without blocking
