TraCIServerAPI_Simulation& TraCIServerAPI_Simulation::operator= ( const TraCIServerAPI_Simulation & s ) [private]

invalidated assignment operator

bool TraCIServerAPI_Simulation::processGet	(	tcpip::Storage &	inputStorage,
		tcpip::Storage &	outputStorage,
		const std::map< MSNet::VehicleState, std::vector< std::string > > &	info,
		bool	withStatus = `true`
	)			throw (traci::TraCIException) `[static]`

Processes a get value command (Command 0xaa: Get Edge 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)
