SWIGTYPE_p_p_ : a Pointer on a Pointer on a Structure ( From C/C++ to Java )

问题

I'm using Swig to generate Java classes.

I need to deal with a pointer on a pointer on a structure.

I have this structure :

struct Model {
    uint32_t serial;    
}

And I have a function in the C/C++ that needs to be wrapped :

void getModel( Model ** model ){
   // instructions...
}

I get as a result this Java class :

public class SWIGTYPE_p_p_Model {
  private long swigCPtr;

  protected SWIGTYPE_p_p_Model(long cPtr, boolean futureUse) {
    swigCPtr = cPtr;
  }

  protected SWIGTYPE_p_p_Model() {
    swigCPtr = 0;
  }

  protected static long getCPtr(SWIGTYPE_p_p_Model obj) {
    return (obj == null) ? 0 : obj.swigCPtr;
  }
}

So my questions are :

1. how can I use this class?

2. How can I make a typemap in Swig to get read of SWIGTYPE_p_p ?
