                                    HttpMessageParserFactory<HttpResponse> responseParserFactory)

Creates new instance of DefaultBHttpClientConnection.

Parameters:

buffersize - buffer size. Must be a positive number.

fragmentSizeHint - fragment size hint.

chardecoder - decoder to be used for decoding HTTP protocol elements. If null simple type cast will be used for byte to char conversion.

charencoder - encoder to be used for encoding HTTP protocol elements. If null simple type cast will be used for char to byte conversion.

constraints - Message constraints. If null MessageConstraints.DEFAULT will be used.

incomingContentStrategy - incoming content length strategy. If null LaxContentLengthStrategy.INSTANCE will be used.

outgoingContentStrategy - outgoing content length strategy. If null StrictContentLengthStrategy.INSTANCE will be used.

requestWriterFactory - request writer factory. If null DefaultHttpRequestWriterFactory.INSTANCE will be used.

responseParserFactory - response parser factory. If null DefaultHttpResponseParserFactory.INSTANCE will be used.

Method Detail

onResponseReceived

protected void onResponseReceived(HttpResponse response)

onRequestSubmitted

protected void onRequestSubmitted(HttpRequest request)

bind

public void bind(java.net.Socket socket)
          throws java.io.IOException

Description copied from class: BHttpConnectionBase

Binds this connection to the given Socket. This socket will be used by the connection to send and receive data.

After this method's execution the connection status will be reported as open and the BHttpConnectionBase.isOpen() will return true.

Overrides:

bind in class BHttpConnectionBase

Parameters:

socket - the socket.

Throws:

java.io.IOException - in case of an I/O error.

isResponseAvailable

public boolean isResponseAvailable(int timeout)
                            throws java.io.IOException

Description copied from interface: HttpClientConnection

Checks if response data is available from the connection. May wait for the specified time until some data becomes available. Note that some implementations may completely ignore the timeout parameter.

Specified by:

isResponseAvailable in interface HttpClientConnection

Parameters:

timeout - the maximum time in milliseconds to wait for data

Returns:

true if data is available; false if there was no data available even after waiting for timeout milliseconds.

Throws:

java.io.IOException - if an error happens on the connection

sendRequestHeader

public void sendRequestHeader(HttpRequest request)
                       throws HttpException,
                              java.io.IOException

Description copied from interface: HttpClientConnection

Sends the request line and all headers over the connection.

Specified by:

sendRequestHeader in interface HttpClientConnection

Parameters:

request - the request whose headers to send.

Throws:

HttpException - in case of HTTP protocol violation

java.io.IOException - in case of an I/O error

sendRequestEntity

public void sendRequestEntity(HttpEntityEnclosingRequest request)
                       throws HttpException,
                              java.io.IOException
