clear()
public void resetQuick()
clear
method if you want to recyle a list
without allocating new backing arrays. This method differs
from reset
in that it does not clear the old
values in the backing array. Thus, it is possible for getQuick
to return stale data if this method is used
and the caller is careless about bounds checking.
