public class SnapshotArray<T> extends Array<T>
begin() between indexes
0 and Array.size at the time begin was called will not be modified until end() is called. If modification of the
SnapshotArray occurs between begin/end, the backing array is copied prior to the modification, ensuring that the backing array
that was returned by begin() is unaffected. To avoid allocation, an attempt is made to reuse any extra array created
as a result of this copy on subsequent copies.
Note that SnapshotArray is not for thread safety, only for modification during iteration.
It is suggested iteration be done in this specific way:
SnapshotArray array = new SnapshotArray();
// ...
Object[] items = array.begin();
for (int i = 0, n = array.size; i < n; i++) {
Object item = items[i];
// ...
}
array.end();
