Bulk operation can be used instead of iteration
Reports single operations inside loops that could be replaced with a bulk method.
Not only are bulk methods shorter, but in some cases they may be more performant as well.
Example:
void test(Collection<Integer> numbers) {
List<Integer> result = new ArrayList<>();
for (Integer i : numbers) {
result.add(i);
}
}
After the fix is applied:
void test(Collection<Integer> numbers) {
List<Integer> result = new ArrayList<>();
result.addAll(numbers);
}
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
UseBulkOperation
The Use Arrays.asList() to wrap arrays option allows to report arrays, even if the bulk method requires a collection. In this case the quick-fix will automatically wrap the array in Arrays.asList()
call.
