Class ServerHandler

java.lang.Object
  org.apache.synapse.transport.nhttp.ServerHandler

All Implemented Interfaces:

org.apache.http.nio.NHttpServiceHandler

public class ServerHandler
extends Object
implements org.apache.http.nio.NHttpServiceHandler

The server connection handler. An instance of this class is used by each IOReactor, to process every connection. Hence this class should not store any data related to a single connection - as this is being shared.

Method Detail

requestReceived

public void requestReceived(org.apache.http.nio.NHttpServerConnection conn)

Process a new incoming request

Specified by:

requestReceived in interface org.apache.http.nio.NHttpServiceHandler

Parameters:

conn - the connection

inputReady

public void inputReady(org.apache.http.nio.NHttpServerConnection conn,
                       org.apache.http.nio.ContentDecoder decoder)

Process ready input by writing it into the Pipe

Specified by:

inputReady in interface org.apache.http.nio.NHttpServiceHandler

Parameters:

conn - the connection being processed

decoder - the content decoder in use

outputReady

public void outputReady(org.apache.http.nio.NHttpServerConnection conn,
                        org.apache.http.nio.ContentEncoder encoder)

Process ready output by writing into the channel

Specified by:

outputReady in interface org.apache.http.nio.NHttpServiceHandler

Parameters:

conn - the connection being processed

encoder - the content encoder in use

commitResponseHideExceptions

public void commitResponseHideExceptions(org.apache.http.nio.NHttpServerConnection conn,
                                         org.apache.http.HttpResponse response)

Commit the response to the connection. Processes the response through the configured HttpProcessor and submits it to be sent out. This method hides any exceptions and is targetted for non critical (i.e. browser requests etc) requests, which are not core messages

Parameters:

conn - the connection being processed

response - the response to commit over the connection

commitResponse

public void commitResponse(org.apache.http.nio.NHttpServerConnection conn,
                           org.apache.http.HttpResponse response)
                    throws IOException,
                           org.apache.http.HttpException

Commit the response to the connection. Processes the response through the configured HttpProcessor and submits it to be sent out. Re-Throws exceptions, after closing connections

Parameters:

conn - the connection being processed

response - the response to commit over the connection

Throws:

IOException - if an IO error occurs while sending the response

org.apache.http.HttpException - if a HTTP protocol violation occurs while sending the response

timeout

public void timeout(org.apache.http.nio.NHttpServerConnection conn)

Handle connection timeouts by shutting down the connections

Specified by:

timeout in interface org.apache.http.nio.NHttpServiceHandler

Parameters:

conn - the connection being processed

connected

public void connected(org.apache.http.nio.NHttpServerConnection conn)

Specified by:

connected in interface org.apache.http.nio.NHttpServiceHandler

responseReady

public void responseReady(org.apache.http.nio.NHttpServerConnection conn)

Specified by:

responseReady in interface org.apache.http.nio.NHttpServiceHandler

closed

public void closed(org.apache.http.nio.NHttpServerConnection conn)

Specified by:

closed in interface org.apache.http.nio.NHttpServiceHandler

markActiveConnectionsToBeClosed

public void markActiveConnectionsToBeClosed()

exception

public void exception(org.apache.http.nio.NHttpServerConnection conn,
                      org.apache.http.HttpException e)

Handle HTTP Protocol violations with an error response

Specified by:

exception in interface org.apache.http.nio.NHttpServiceHandler

Parameters:

conn - the connection being processed

e - the exception encountered

exception

public void exception(org.apache.http.nio.NHttpServerConnection conn,
                      IOException e)

Handle IO errors while reading or writing to underlying channels

Specified by:

exception in interface org.apache.http.nio.NHttpServiceHandler

Parameters:

conn - the connection being processed

e - the exception encountered
