+    An abstract superclass for all unboxed integer classes.
+    In contrast to normal arrays (which store pointers to their elements),
+    unboxedIntegerArrays store the values in a dense & compact way. 
+    Since the representation fits corresponding underlying C-language representations,
+    these are also useful to pass bulk data to c primitive code.
