Member Function Documentation

virtual void onReady ( )
protectedvirtual

Derived responders implement this method to format and send the XML-RPC result. It is called when the service procedure has finished. Use beginResult(), advanceResult() and finishResult() to format the XML-RPC result.

Implements Responder.

virtual void onCancel ( )
protectedvirtual

Derived responders implement this method to cancel all operations.

Implements Responder.

virtual void onFault ( const Fault fault)
protectedpure virtual

Derived responders implement this method to format and send the XML-RPC fault result. It is called when the service procedure has failed. Use beginResult(), advanceResult() and finishResult() to format the XML-RPC result.

virtual void onResult ( )
protectedpure virtual

Derived responders implement this method to format and send the XML-RPC result. It is called when the service procedure has finished. Use beginResult(), advanceResult() and finishResult() to format the XML-RPC result.

void beginMessage ( std::istream &  is)
protected

This method is used by derived responders to begin parsing a XML-RPC message from a std::istream.

bool parseMessage ( )
protected

This method is used by derived responders to parse a XML-RPC message. Each call consumes the available data from the std::istream set with beginMessage() and returns true if no more message data needs to be parsed, either because the message is complete or an error occured.

void finishMessage ( System::EventLoop loop)
protected

This method is used by derived responders after the XML-RPC message has been parsed by parseMessage(). This will execute the service procedure.

void beginResult ( std::ostream &  os)
protected

This method is used by derived responders in onResult() and onError() to begin formatting a XML-RPC result to a std::ostream.

bool advanceResult ( )
protected

This method is used by derived responders in onResult() and onError() to format a XML-RPC result. Each call generates a chunk of the result and returns true if the message is complete.

void finishResult ( )
protected

This method is used by derived responders in onResult() and onError() to format the end of a XML-RPC result. It is called after advanceResult() returns true.

void setFault ( int  rc,
const char *  msg 
)
protected

This method is used by derived responders to indicate that the service procedure should not be executed, but a fault result be generated instead.
