Interface CalculateIsolineCallback

CalculateIsolineCallback (API Reference)

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 CalculateIsolineCallback
```
A function which is called by the RoutingEngine after isoline calculation has completed. It is always called on the main thread. The first argument is the error in case of a failure. It is null for an operation that succeeds. The second argument holds a list of calculated isolines. The list is null in case of an error. The size of the list matches the size of the provided sdk.routing.IsolineOptions.range_values: For each range limit, one isoline is calculated.
