Is it possible to instantiate an interface class from an AddressPointer?

[PatrickWegmann]

I have a lib where i get the actual instance after the Create function,

ThingClass* instance_;

int err = CreateFoo (&instance_);

instance_->Initialize (&param);

is there a way to convert this Pointer o an interface class?

sorry for this noob question?

Is this C++? It is possible to call C++ from jnr-ffi but it is tricky due to the mangling that compilers do. You might be better exporting some C functions that mirror the parts of the C++ code you want to call from Java.
