Thread Subject: calling a java method that requires a reference in its argumets

Hi All,

I'm using some java classes and one of the methods looks
like this:

void getROI (unsigned &x, unsigned &y, unsigned &xSize,
unsigned &ySize)

e.g. it has no return value but asks for references to the
variable to change its value.

Is there any way in matlab to generate such references? Or
any other way to call this function.

Thanks
Roy
