Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface TrafficFlowQueryCallback
```
Callback passed to following functions: TrafficEngine.queryForFlow(GeoBox, TrafficFlowQueryOptions, TrafficFlowQueryCallback) TrafficEngine.queryForFlow(GeoCircle, TrafficFlowQueryOptions, TrafficFlowQueryCallback) TrafficEngine.queryForFlow(GeoCorridor, TrafficFlowQueryOptions, TrafficFlowQueryCallback) The method will be called on the main thread when a search call has been completed. The first argument is the error in the case of the failure. It is null for an operation that succeeds. The second argument is the list of flow items in the case of the success. It is null in case of an error.
