Describe the aim of the proposed feature?
When an indoor localization sensor sends x,y coordinates the system must move
the related object (usually a person) to this coords and check three cases:
- the person was in no zone and move inside a zone (enter)
- the person was in a zone and moves to another zone (exit+enter)
- the person was in a zone and moves nowhere (exits)
Describe how you would implement this feature
we need a data stracture to track if an object is in a zone or not (implemented
in EnvObjectLogic?)
translate a coordinate to a list of zones it belongs (in a LocationEvent?)
check the object data structure against the new list of zones
fire the right PersonEntersZone/PersonExitsZone events (add to this event also
count of people in the zone)
NOTE: PersonEntersZone/PersonExitsZone is the old definition. Now Person are
extensions of objects so is better to define a LocationEvent which takes in
input a coordinate and fires others ZoneEvent for enter/exit triggers.
