BooleanList
is backed by me, so that any changes
in the returned list are reflected in me, and vice-versa. The returned
list supports all of the optional operations that I support.
Note that when fromIndex == toIndex
, the
returned list is initially empty, and when fromIndex == 0
&& toIndex == size()
the returned list is
my "improper" sublist, containing all my elements.
The semantics of the returned list become undefined if I am structurally
modified in any way other than via the returned list.subList

true
iff that is an BooleanList
that contains the same elements in the same order as me.
In other words, returns true
iff that is
a BooleanList
that has the same size
as me,
and for which the elements returned by its
iterator
are equal (==
) to
the corresponding elements within me.

different implementations of the BooleanList
interface.)equals

If a collection refuses to add the specified element for any reason
other than that it already contains the element, it must
throw an exception (rather than simply returning false).
This preserves the invariant that a collection always contains the
specified element after this call returns.add

The returned array will be independent of me, so that callers may
modify that returned array without modifying this collection.
When I guarantee the order in which elements are returned by an
iterator
, the returned array will contain elements
in the same order.toArray
