public ShortList subList(int fromIndex, int toIndex)
ShortList
ShortList
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.

the returned listtoIndex

public boolean equals(Object obj)
ShortList
true
iff that is an ShortList
that contains the same elements in the same order as me.
In other words, returns true
iff that is
an ShortList
that has the same size
as me,
and for which the elements returned by its
iterator
are equal (==
) to
the corresponding elements within me.
(This contract ensures that this method works properly across
different implementations of the ShortList
interface.)
equals
in interface ShortList
public int hashCode()
ShortList
ShortList
is defined to be the
result of the following calculation:
int hash = 1; for(ShortIterator iter = iterator(); iter.hasNext(); ) { short value = iter.next(); hash = 31*hash + (int)(value ^ (value >>> 32)); }This contract ensures that this method is consistent with
equals
and with the
hashCode
method of a List
of Short
s.

true
iff I changed as a result of this call.
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.

The returned array will be independent of me,
so that callers may modify that

When I guarantee the order in which
elements are returned by an iterator
,
the returned array will contain elements in the
same order.
