[sumo-user] some question on detector implement!

[<wei...@ho...>]

hello,
     I have some question follows.
     1.the define in MSDetectorHaltingContainerWrapper.h we know that 
SDetectorHaltingMapWrapper derived from the MSUpdateEachTimestep template.
struct MSDetectorHaltingMapWrapper
    :
//     public MSDetectorMapWrapper< T >
//     , public MSUpdateEachTimestep< MSDetectorHaltingMapWrapper< T > >
    public MSDetectorVehicleInitMapWrapper< DetectorContainer::E3Halting >
    , public MSUpdateEachTimestep< MSDetectorHaltingMapWrapper >

but here  MSUpdateEachTimestep is used another times, why?
    typedef MSDetectorHaltingMapWrapper HaltingsMap;

    typedef MSUpdateEachTimestep< HaltingsMap > UpdateE3Haltings;

     2.I can't find the using of MSTravelcostDetector template, why?
     3. As is said in manual, lanestate is an kind of extend detector, what 
is the
difference between e1,e2,e3,and lanestate?
     4.can you explain the function of e1,e2,e3collector, I think it is a 
class type container, which present a collection of the detector of a 
lane,is it true?
     5.I am reading the 0.9.2 src, is really a big change.
