Query<C extends GpsPointsView<GpsPoint> , R extends QueryResult> class
abstract
Abstract generic ancestor class for queries parametrized for collection type
C
and result type R
.
Since queries may have specific implementations for particular collection types, they are generics parametrized for collection type.
The goal is to be able to send queries to a separate isolate and get the results back efficiently. This requires the Query children to store internally a representation that is cheap to transfer over an isolate port.
