/**
 * nsIMutableArray
 * A separate set of methods that will act on the array. Consumers of
 * nsIArray should not QueryInterface to nsIMutableArray unless they
 * 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.
