[vtkusers] SetJavaArray without memcpy

Dear VTK users;
I have modified vtkWrapJava.c 's HandleDataArray's method with the
following change:
fprintf(fp," op->SetVoidArray((void*)tempArray0,length,0);
\n",jfromtype);
/*
fprintf(fp," memcpy(op->GetVoidPointer(0), tempArray0,
length*sizeof(%s));\n", type);
fprintf(fp," env->Release%sArrayElements(id0,(j%s *)tempArray0,0);
\n", jfromtype, jtype);
*/
I want to do this so I can do some image processing in Java without
duplicating memory. This works great, but I haven't quite figured
out how or where to place the Release*ArrayElements. Obviously I'll
need to modify vtkParseJava.c and place some way. Is it best to put
the Release elements call in a finalize method or is there a more
appropriate/logical place?
Thanks,
Sumit
