Detailed Description

Writes information about the green durations of a tls.

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

Writes the output if a change occured.

Called in each tme step, this class computes which link have red since the last tls switch and writes the information about their green duration into the given stream.

Information whether a link had green and since when is stored in "myPreviousLinkStates".

Parameters:

[in] currentTime The current simulation time

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

Exceptions:

ProcessError

not here

See also:: Command

Implements Command.
