41 SignedIntegerArrays store 32bit signed integers in the range -16r80000000..16r7FFFFFFF. |
|
42 In contrast to normal arrays (which store pointers to their elements), |
|
43 signedIntegerArrays store the values in a dense & compact way. |
|
44 Since the representation fits the underlying C-language systems representation |
|
45 of signed int32's, this is also useful to pass bulk data to c primitive code. |
