extracting data from a field

I am trying to traverse through the structure of a field and extract the data
for verification purposes.

Here is a snippet of code.

DataImpl mofStructure = plain.open(args[0]); //open and load netcdf file
FieldImpl mofField = (FieldImpl)mofStructure; //convert to fieldimpl
Data mofData = mofField.getSample(0);  //get first sample

The data object received from 'getSample()' is of type Real.
It should be tuple however I cannot cast it to Tuple and therefore cannot
access the data (through getData() from tuple).
How do I access the data?
