add new traci domains #6147

Open namdre opened 4 years ago

namdre commented 4 years ago

Currently we use 15 domains - last 4 bits of the command (with one left for expansion) The first 4 bits are used to distinguish

CMD_SUBSCRIBE_XXX_CONTEXT
RESPONSE_SUBSCRIBE_XXX_CONTEXT
CMD_GET_XXX_VARIABLE
RESPONSE_GET_XXX_VARIABLE
CMD_SET_XXX_VARIABLE
CMD_SUBSCRIBE_XXX_VARIABLE
RESPONSE_SUBSCRIBE_XXX_VARIABLE

This leave one unused bit which we can use to double the available domains. We could add:

[x] busstop
[x] parkingarea
[x] chargingstation
[x] routeprobe
[x] calibrator
[x] rerouter
[x] variablespeedsign
[x] meandata
[x] overheadwire

Still missing:

[ ] subscriptions (context and otherwise)

API questions

detectors (routeProbe, meanData) aggregated data and could either retrieve the (complete) last data interval or the (incomplete) current interval. Either
- add two methods getLastXXX, getCurrentXXX (pro: better for subscriptions)
- ~~add one method with extra parameter getXXX(..., bool current)~~
meandata records lots of things and there are many alternatives for returning data
- retrieve a struct will all data for a given edgeID
- retrieve a result list for all edges (one method for each attribute)
routeProbe and vss have paired data (route, count), (time, speed)
- ~~add two methods (getRouteIDs, getRouteCounts)~~
- add methods that return a list of pairs (C++) / tuples (python)

subscriptions still open, separate tickets for the remaining parts https://github.com/eclipse/sumo/issues/6147#issuecomment-675320599
