compare
fun compare(
aa: ApplicationInfo!,

): Int
| Parameters |
o1 |
the first object to be compared. |
o2 |
the second object to be compared. |
| Return |
Int |
a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second. |
| Exceptions |
java.lang.NullPointerException |
if an argument is null and this comparator does not permit null arguments |
java.lang.ClassCastException |
if the arguments' types prevent them from being compared by this comparator. |
