Detailed Description

Writes the switch times of a tls into a file when the tls switches.

Todo:: Revalidate this - as tls are not seting the link information directly ater being switched, the computed information may be delayed

Member Function Documentation

SUMOTime Command_SaveTLSSwitchStates::execute ( SUMOTime currentTime ) throw (ProcessError) [virtual]

Writes the state of the tls if a change occured.

If the state or the active program has changed, the state is written to the output device.

Returns always 1.

Parameters:

[in] currentTime The current simulation time

Returns:: Always 1 (will be executed in next time step)

Exceptions:

ProcessError

not here

See also:: Command

Todo:: Here, a discrete even (on switch / program change) would be appropriate

Implements Command.
