The value to be retrieved.
To retrieve a value from the extra class memory, specify the positive,
zero-based byte offset of the value to be retrieved.
Valid values are in the range zero through the number of bytes of extra class memory,
minus four; for example, if you specified 12 or more bytes of extra class memory,
a value of 8 would be an index to the third integer.
