Method Details

onResponseReceived

protected void onResponseReceived(ClassicHttpResponse response)

onRequestSubmitted

protected void onRequestSubmitted(ClassicHttpRequest request)

bind

public void bind(Socket socket)
          throws 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:

IOException - in case of an I/O error.

sendRequestHeader

                       throws HttpException,
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

IOException - in case of an I/O error

sendRequestEntity

public void sendRequestEntity(ClassicHttpRequest request)
                       throws HttpException,
IOException

Description copied from interface: HttpClientConnection

Sends the request entity over the connection.

Specified by:

sendRequestEntity in interface HttpClientConnection

Parameters:

request - the request whose entity to send.

Throws:

HttpException - in case of HTTP protocol violation

IOException - in case of an I/O error

isConsistent

public boolean isConsistent()

Description copied from interface: HttpClientConnection

Checks whether this connection is in a consistent state.

Specified by:

isConsistent in interface HttpClientConnection

Returns:

true if the connection is known to be in a inconsistent state and cannot be re-used.

Specified by:

terminateRequest in interface HttpClientConnection

Parameters:

request - the request to be terminated prematurely.

Throws:

HttpException

IOException
