Detailed Description

A fixed traffic light logic.

The implementation of a simple traffic light which only switches between it's phases and sets the lights to red in between. Some functions are called with an information about the current step. This is needed as a single logic may be used by many junctions and so the current step is stored within them, not within the logic.

void MSTrafficLightLogic::adaptLinkInformationFrom ( const MSTrafficLightLogic &  logic  )  throw () [virtual, inherited]

Applies information about controlled links and lanes from the given logic.

If we load a logic after the network has been loaded, we do not get the information about controlled links afterwards. We have to copy them from a previously loaded logic.

Parameters:
[in] logic The logic to use the information about controlled links/lanes from
