An abstract superclass for all unboxed integer classes.
|
|
42 |
In contrast to normal arrays (which store pointers to their elements),
|
|
43 |
unboxedIntegerArrays store the values in a dense & compact way.
|
|
44 |
Since the representation fits corresponding underlying C-language representations,
|
|
45 |
these are also useful to pass bulk data to c primitive code.
