Method Summary | |
---|---|
boolean |
add(int element)
Appends the specified element to the end of me (optional operation). |
void |
add(int index,
int element)
Inserts the specified element at the specified position (optional operation). |
boolean |
addAll(int index,
IntCollection collection)
Inserts all of the elements in the specified collection into me, at the specified position (optional operation). |
boolean |
equals(java.lang.Object that)
Returns true iff that is an IntList
that contains the same elements in the same order as me. |
int |
get(int index)
Returns the value of the element at the specified position within me. |
int |
hashCode()
Returns my hash code. |
int |
indexOf(int element)
Returns the index of the first occurrence of the specified element within me, or -1 if I do not contain
the element. |
IntIterator |
iterator()
Returns an iterator over all my elements,
in the appropriate sequence. |
int |
lastIndexOf(int element)
Returns the index of the last occurrence of the specified element within me, or -1 if I do not contain the element. |
IntListIterator |
listIterator()
Returns a bidirectional iterator
over all my elements, in the appropriate sequence. |
IntListIterator |
listIterator(int index)
Returns a bidirectional iterator
over all my elements, in the appropriate sequence,
starting at the specified position. |
int |
removeElementAt(int index)
Removes the element at the specified position in (optional operation). |
int |
set(int index,
int element)
Replaces the element at the specified position in me with the specified element (optional operation). |
IntList |
subList(int fromIndex,
int toIndex)
Returns a view of the elements within me between the specified fromIndex, inclusive, and toIndex, exclusive. |

boolean add(int element)
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.

true
iff that is an IntList
that contains the same elements in the same order as me.
In other words, returns true
iff that is
an IntList
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 IntList
interface.)

IntList
is defined to be the
result of the following calculation:
int hash = 1; for(IntIterator iter = iterator(); iter.hasNext(); ) { hash = 31*hash + iter.next(); }This contract ensures that this method is consistent with
equals
and with the
hashCode
method of a List
of Integer

specified index indicates the first
element that would be returned by an initial
call to the
next
method. An initial call to the
previous
method would return the element with the specified
index minus one.

IntList
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.
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
java.lang.IndexOutOfBoundsException
- if either specified index is out of range
