bool TraCIServerAPI_Junction::processGet	(	tcpip::Storage &	inputStorage,
		tcpip::Storage &	outputStorage,
		bool	withStatus = true
	)			throw (traci::TraCIException) [static]

Processes a get value command (Command 0xa9: Get Junction Variable).

Parameters:

[in]	inputStorage	The storage to read the command from
[out]	outputStorage	The storage to write the result to
[in]	withStatus	Whether the status message shall be written (not in subscription)
