public DoubleList subList(int fromIndex, int toIndex)
DoubleList
DoubleList
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
in interface DoubleList
fromIndex
- the smallest index (inclusive) in me that appears in
the returned listtoIndex
- the largest index (exclusive) in me that appears in the
returned list
public boolean equals(java.lang.Object obj)
DoubleList
true
iff that is an DoubleList
that contains the same elements in the same order as me.
In other words, returns true
iff that is
an DoubleList
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 DoubleList
interface.)

obj

true
iff that is an DoubleList
that contains the same elements in the same order as mepublic int hashCode()
DoubleList
DoubleList
is defined to be the
result of the following calculation:
int hash = 1; for(DoubleIterator iter = iterator(); iter.hasNext(); ) { double 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 Double
s.
