Is there a way to reference the engine from a linker?

[Paulo Lopes]

Hi,

I'm writing a guarded linker to allow custom casting from JSObject to Vertx
custom types. So far so good, the basic tests seem to work but I think I'm
writing too much boiler plate code as I need in many times to have an
intermediate conversion from JSObject to Map or List.

So I know that in the engine I could call Java.asJSONCompatible() but I
don't see how I could get a reference to the engine in the linker.

Could anyone see a way or let me know if there is a open API to do this?

Thanks!
Paulo
