+ * own the array.
+ *
+ * As above, it is legal to add null elements to the array. Note also
+ * that null elements can be created as a side effect of
+ * insertElementAt(). Conversely, if insertElementAt() is never used,
+ * and null elements are never explicitly added to the array, then it
+ * is guaranteed that queryElementAt() will never return a null value.
+ *
+ * Any of these methods may throw NS_ERROR_OUT_OF_MEMORY when the
+ * array must grow to complete the call, but the allocation fails.
