Method Detail

connected

void connected(NHttpClientConnection conn,
               Object attachment)
Deprecated. 
Triggered when a new outgoing connection is created.

Parameters:
conn - new outgoing HTTP connection.
attachment - an object that was attached to the session request

requestReady

void requestReady(NHttpClientConnection conn)
Deprecated. 
Triggered when the connection is ready to accept a new HTTP request. The protocol handler does not have to submit a request if it is not ready.

Parameters:
conn - HTTP connection that is ready to accept a new HTTP request.
See Also:
NHttpClientConnection

responseReceived

void responseReceived(NHttpClientConnection conn)
Deprecated. 
Triggered when an HTTP response is received. The connection passed as a parameter to this method is guaranteed to return a valid HTTP response object.

If the response received encloses a response entity this method will be followed by a series of inputReady(NHttpClientConnection, ContentDecoder) calls to transfer the response content.

Parameters:
conn - HTTP connection that contains an HTTP response
See Also:
NHttpClientConnection

inputReady

void inputReady(NHttpClientConnection conn,
                ContentDecoder decoder)
Deprecated. 
Triggered when the underlying channel is ready for reading a new portion of the response entity through the corresponding content decoder.

If the content consumer is unable to process the incoming content, input event notifications can be temporarily suspended using IOControl interface.

Parameters:
conn - HTTP connection that can produce a new portion of the incoming response content.
decoder - The content decoder to use to read content.
See Also:
NHttpClientConnection, ContentDecoder, IOControl

outputReady

void outputReady(NHttpClientConnection conn,
                 ContentEncoder encoder)
Deprecated. 
Triggered when the underlying channel is ready for writing a next portion of the request entity through the corresponding content encoder.

If the content producer is unable to generate the outgoing content, output event notifications can be temporarily suspended using IOControl interface.

Parameters:
conn - HTTP connection that can accommodate a new portion of the outgoing request content.
encoder - The content encoder to use to write content.
See Also:
NHttpClientConnection, ContentEncoder, IOControl

exception

void exception(NHttpClientConnection conn,
               IOException ex)
Deprecated. 
Triggered when an I/O error occurs while reading from or writing to the underlying channel.

Parameters:
conn - HTTP connection that caused an I/O error
ex - I/O exception

exception

void exception(NHttpClientConnection conn,
               HttpException ex)
Deprecated. 
Triggered when an HTTP protocol violation occurs while receiving an HTTP response.

Parameters:
conn - HTTP connection that caused an HTTP protocol violation
ex - HTTP protocol violation exception

timeout

void timeout(NHttpClientConnection conn)
Deprecated. 
Triggered when no input is detected on this connection over the maximum period of inactivity.

Parameters:
conn - HTTP connection that caused timeout condition.

closed

void closed(NHttpClientConnection conn)
Deprecated. 
Triggered when the connection is closed.

Parameters:
conn - closed HTTP connection.
