Hi, Myoungkyu,
Yes, you can pass an X10 object reference. In your example, the variable
myClass will have the type x10aux::ref<MyClass>, and you can write your
functions accordingly. When in doubt, just declare a method foo() in X10
and look at the generated C++ code -- as long as you mimic that in your
code, you can access X10 objects.
