Well, I Know very little about Java, and this is an MFC/CPP Forum. In CPP a default argument is declared in the function declaration in a class, as in
class CMyClass{ int MyFunct(int Arg=0);};
This is a Declaration that MyClass has a Method named'MyFunct', which returns an int, and Optionally takes a Parameter (Arg), and, that when I call this function without a parameter, that 0 will be assumed. You make those declarations in a 'Header File' You Implement the function in the Implementation File,(Typically a CPP File) were you actually Implement the function:
int MyClass::MyFunct(int Arg)
if(Arg==0)return 1;
else return 2;
}
The above means that when using the class, you write:
MyClass myclass;// Instantiate the class.
myclass.MyFunct();//Will return 1, an Argument 0 is assumed
myclass.MyFunct(0);// will return 1, the Argument 0 is specified
myclass.MyFunct(12);//returns 2, as per Calculation, Arg !-0
Your Marshalling Software beteween Java and CPP should give more details. :)
