Hi,

I'm writing a method along the lines of:

double[] extractDataFrom(GridDatatype grid);

where the GridDatatype is being passed to me by "foreign" code out of my
control.  Do I have any way of telling whether the GridDatatype is
"enhanced", i.e. whether scale/offset/missing attributes are
automatically applied when I extract data?

And does it matter?  Can I program defensively to take care of both
situations (enhanced and not enhanced)?  I'm worried that simply
applying convertScaleOffsetMissing() to a value from an enhanced
GridDatatype might actually apply the enhancements twice and hence give
me the wrong answer.

Thanks,
Jon
