Method Detail

processOp

protected abstract ServiceHandshake.InitResult processOp(DataChannel channel)
                                                  throws IOException

Incrementally process the operation. The operation may require multiple passes since we are presumed to be in non-blocking mode. This function returns one of the following: InitResult.READ: operation is not complete; more data needed InitResult.FAIL: operation was rejected or otherwise failed the underlying data channel has been closed. InitResult.DONE: operation has completed

Throws:

IOException

fillBuffer

protected ServiceHandshake.InitResult fillBuffer(DataChannel channel,
                                                 ByteBuffer buffer)
                                          throws IOException

Helper function to read until the buffer is full.

Throws:

IOException

sendBuffer

protected ServiceHandshake.InitResult sendBuffer(DataChannel channel,
                                                 ByteBuffer buffer)
                                          throws IOException

Helper function to write the contents of the buffer. We make the simplifying assumption here that we will be able to write as much as we want (within reason).

Throws:

IOException
