Deprecated. 
Asserts if the connection is open.

Throws:
IllegalStateException - if the connection is not open.

createEntityDeserializer

protected EntityDeserializer createEntityDeserializer()
Deprecated. 
Creates an instance of EntityDeserializer with the LaxContentLengthStrategy implementation to be used for de-serializing entities received over this connection.

This method can be overridden in a super class in order to create instances of EntityDeserializer using a custom ContentLengthStrategy.

Returns:
HTTP entity deserializer

createEntitySerializer

protected EntitySerializer createEntitySerializer()
Deprecated. 
Creates an instance of EntitySerializer with the StrictContentLengthStrategy implementation to be used for serializing HTTP entities sent over this connection.

This method can be overridden in a super class in order to create instances of EntitySerializer using a custom ContentLengthStrategy.

Returns:
HTTP entity serialzier.

createHttpRequestFactory

protected HttpRequestFactory createHttpRequestFactory()
Deprecated. 
Creates an instance of DefaultHttpRequestFactory to be used for creating HttpRequest objects received by over this connection.

This method can be overridden in a super class in order to provide a different implementation of the HttpRequestFactory interface.

Returns:
HTTP request factory.

createRequestParser

protected HttpMessageParser<HttpRequest> createRequestParser(SessionInputBuffer buffer,
                                                             HttpRequestFactory requestFactory,
                                                             HttpParams params)
Deprecated. 
Creates an instance of HttpMessageParser to be used for parsing HTTP requests received over this connection.

This method can be overridden in a super class in order to provide a different implementation of the HttpMessageParser interface or to pass a different implementation of the LineParser to the DefaultHttpRequestParser constructor.

Parameters:
buffer - the session input buffer.
requestFactory - the HTTP request factory.
params - HTTP parameters.
Returns:
HTTP message parser.

createResponseWriter

protected HttpMessageWriter<HttpResponse> createResponseWriter(SessionOutputBuffer buffer,
                                                               HttpParams params)
Deprecated. 
Creates an instance of HttpMessageWriter to be used for writing out HTTP responses sent over this connection.

This method can be overridden in a super class in order to provide a different implementation of the HttpMessageWriter interface or to pass a different implementation of LineFormatter to the the default implementation HttpResponseWriter.

Parameters:
buffer - the session output buffer
params - HTTP parameters
Returns:
HTTP message writer

createConnectionMetrics

protected HttpConnectionMetricsImpl createConnectionMetrics(HttpTransportMetrics inTransportMetric,
                                                            HttpTransportMetrics outTransportMetric)
Deprecated. 
Since:
4.1

init

protected void init(SessionInputBuffer inbuffer,
                    SessionOutputBuffer outbuffer,
                    HttpParams params)
Deprecated. 
Initializes this connection object with SessionInputBuffer and SessionOutputBuffer instances to be used for sending and receiving data. These session buffers can be bound to any arbitrary physical output medium.

This method will invoke createHttpRequestFactory(), createRequestParser(SessionInputBuffer, HttpRequestFactory, HttpParams) and createResponseWriter(SessionOutputBuffer, HttpParams) methods to initialize HTTP request parser and response writer for this connection.

Parameters:
inbuffer - the session input buffer.
outbuffer - the session output buffer.
params - HTTP parameters.

receiveRequestHeader

Deprecated. 
Description copied from interface: HttpServerConnection
Receives the next request entity available from this connection and attaches it to an existing request.

Specified by:

Throws:
HttpException - in case of HTTP protocol violation
IOException - in case of an I/O error

doFlush

protected void doFlush()
                throws IOException
Deprecated.

IOException

flush

public void flush()
           throws IOException
Deprecated. 
Description copied from interface: HttpServerConnection
Sends all pending buffered data over this connection.

Specified by:
flush in interface HttpServerConnection
Throws:

sendResponseHeader

public void sendResponseHeader(HttpResponse response)
                        throws HttpException,
                               IOException
Deprecated.

sendResponseEntity

public void sendResponseEntity(HttpResponse response)
                        throws HttpException,
                               IOException
Deprecated. 
Description copied from interface: HttpServerConnection
Sends the response entity of a response over this connection.

Specified by:
sendResponseEntity in interface HttpServerConnection
Parameters:
response - the response whose entity to send.
Throws:
HttpException - in case of HTTP protocol violation
IOException - in case of an I/O error

isEof

protected boolean isEof()
Deprecated. 

isStale

public boolean isStale()
Deprecated. 
Description copied from interface: HttpConnection
Checks whether this connection has gone down. Network connections may get closed during some time of inactivity for several reasons. The next time a read is attempted on such a connection it will throw an IOException. This method tries to alleviate this inconvenience by trying to find out if a connection is still usable. Implementations may do that by attempting a read with a very small timeout. Thus this method may block for a small amount of time before returning a result. It is therefore an expensive operation.

Specified by:
isStale in interface HttpConnection
Returns:
true if attempts to use this connection are likely to succeed, or false if they are likely to fail and this connection should be closed

getMetrics

public HttpConnectionMetrics getMetrics()
Deprecated. 
Description copied from interface: HttpConnection
Returns a collection of connection metrics.

Specified by:
getMetrics in interface HttpConnection
Returns:
HttpConnectionMetrics
