Method Detail

invokeAtSourceConnectionInitiation

void invokeAtSourceConnectionInitiation(String metadata)

Invoked when source connection is initiated.

Parameters:

metadata - unique string key to identify the connection

invokeAtSourceConnectionTermination

void invokeAtSourceConnectionTermination(String metadata)

Invoked when source connection is terminated.

Parameters:

metadata - unique string key to identify the connection

invokeAtTargetConnectionInitiation

void invokeAtTargetConnectionInitiation(String metadata)

Invoked when target connection is initiated.

Parameters:

metadata - unique string key to identify the connection

invokeAtTargetConnectionTermination

void invokeAtTargetConnectionTermination(String metadata)

Invoked when target connection is terminated.

Parameters:

metadata - unique string key to identify the connection

invokeAtSourceRequestReceiving

void invokeAtSourceRequestReceiving(HttpCarbonMessage carbonMessage)

Invoked when source request is started receiving at source handler.

Parameters:

carbonMessage - newly created carbon message.

invokeAtSourceRequestSending

void invokeAtSourceRequestSending(HttpCarbonMessage carbonMessage)

Invoked when source request is started sending to the message processor.

Parameters:

carbonMessage - client request (i.e headers, property and message body)

invokeAtTargetRequestReceiving

void invokeAtTargetRequestReceiving(HttpCarbonMessage carbonMessage)

Invoked when the request is received again to the transport level after being processed at message processor.

Parameters:

carbonMessage - processed (or mediated) request (i.e headers, properties and message body)

invokeAtTargetRequestSending

void invokeAtTargetRequestSending(HttpCarbonMessage carbonMessage)

Invoked when the request is started sending to the backend.

Parameters:

carbonMessage - sent request (i.e the message is already had started to send to backend) So no message body will be available. Even though the headers and properties are available, manipulating them won't change the request send to the back end (because the headers are already been send to the backend)

invokeAtTargetResponseReceiving

void invokeAtTargetResponseReceiving(HttpCarbonMessage carbonMessage)

Invoked when target response is started receiving at target handler.

Parameters:

carbonMessage - newly created carbon message.

invokeAtTargetResponseSending

void invokeAtTargetResponseSending(HttpCarbonMessage carbonMessage)

Invoked when target response is started sending to the message processor.

Parameters:

carbonMessage - target response (i.e headers, property and message body)

invokeAtSourceResponseReceiving

void invokeAtSourceResponseReceiving(HttpCarbonMessage carbonMessage)

Invoked when the response is received again to the transport level after being processed at message processor.

Parameters:

carbonMessage - processed (or mediated) response (i.e headers, properties and message body)

invokeAtSourceResponseSending

void invokeAtSourceResponseSending(HttpCarbonMessage carbonMessage)

Invoked when the response is started sending to the client.

Parameters:

carbonMessage - sent response (i.e with empty message body. similar carbon message to}

handlerName

String handlerName()

Gives handler name.
