It looks good to solve problems that can occur with Java and Scala using
interfaces like `S2[Edge, Vertex, Graph] Like`.
Also, providing the `CompletableFuture` that can be used as a standard
interface in Java is very convenient for users as below.
`` `
def getEdgesJava (q: Query): CompletableFuture [StepResult] =
getEdges (q) .toJava.toCompletableFuture
`` `
> Create Interface for S2Edge/S2Vertex/S2Graph.

> h2. Problem Statement
> S2Graph’s entire code base is dependent on S2Edge/S2Vertex/S2Graph class.
> Even though lots of code touch theses two class, there is no interface
> defined currently. This means lots of code is interact with these class in
> different way all by their own way, and this make extremely hard to make any
> change on these two classes.
> For example, I was working on S2GRAPH-80 to provide java client, and there
> are too many places to be changed since all theses places use concrete
> implementation class S2Edge/S2Vertex/S2Graph, not the interfaces. Not just
> for S2GRAPH-80, but any other issues that need to change theses classes would
> benefit by communicating through interface.
> h2. Suggestion
> Define interface and change code base to communicate through theses
> interfaces.
> # Create interface S2Edge/S2Vertex/S2Graph that implement Tinkerpop’s
> Edge/Vertex/Graph interface
> # Extract tinkerpop interface related implementations
> # Change caller of S2Edge/S2Vertex/S2Graph to call interface rather than
> concrete implementation.
