public static class ProductData.UInt extends ProductData.Int
UInt class is a ProductData specialisation for unsigned 32-bit integer fields.
Internally, data is stored in an array of the type int[].
In order to preserve the accuracy for the unsigned int value range the
getElemUIntAt method should be used to retrieve the data stored in this value instead of accessing
the data array directly.
Another method is to mask each of the array elements in order to get the unsigned type in the following way:
int[] data = (int[]) value.getRaster();
for (int i = 0; i %lt; data.length; i++) {
long value = data[i] & 0xffffffffL;
...

IMPORTANT NOTE: This method returns the data element unchanged as it is sinternally stored (a 32-bit
signed integer) and thus can also return negative values. Use getElemUIntAt which returns
unsigned long values only.
