internalHandleResponse

protected void internalHandleResponse(InetSocketAddress responseFrom,
                                      Transport transport,
                                      ByteBuffer[] response)

Description copied from class: AbstractCAResponseHandler

Called after header is parsed by parseHeader() method.

Specified by:

internalHandleResponse in class AbstractCAResponseHandler

handleResponse

public void handleResponse(InetSocketAddress responseFrom,
                           Transport transport,
                           ByteBuffer[] response)

Description copied from class: AbstractCAResponseHandler

NOTE: (Extended) header buffer size validation should have been already done. response is array of maximum of 2 elments: #UDP: contains whole response #TCP: first element contains complete standard or extended response message header, second whole payload. No buffer size checking is done.

Specified by:

handleResponse in interface ResponseHandler

Overrides:

handleResponse in class AbstractCAResponseHandler

Parameters:

responseFrom - remove address of the responder, null if unknown.

transport - response source transport.

response - array of response messages to handle. First buffer in array has to contain whole (extended) message header.
