Constructor Detail

### ChunkedOutputStream

    public ChunkedOutputStream(byte[] buffer,
                               java.io.DataOutputStream out)

  Create a chunk encoder, using the provided buffer.
  Parameters:
    `buffer` - The buffer to use (determines the default chunk size).
    `put` - The DataOutputStream to write encoded data to.

### ChunkedOutputStream

    public ChunkedOutputStream(java.io.DataOutputStream out)

  Create a chunk encoder.
  Parameters:
    `out` - The DataOutputStream to write to.

Method Detail

### sendClose

    protected void sendClose()
                      throws java.io.IOException

  Send the close chunk.

### sendChunk

    protected void sendChunk(byte[] b,
