java.util
Class AbstractList.SubList  

java.lang.Object
  java.util.AbstractCollection
      java.util.AbstractList
          java.util.AbstractList.SubList

All Implemented Interfaces:

Collection, java.lang.Iterable, List

Direct Known Subclasses:

AbstractList.RandomAccessSubList

Enclosing class:

AbstractList

---

private static class AbstractList.SubList

extends AbstractList

This class follows the implementation requirements set forth in AbstractList.subList(int, int) 55 . It matches Sun's implementation by using a non-public top-level class in the same package.

Field Detail

backingList

final AbstractList backingList

The original list.

---

offset

final int offset

The index of the first element of the sublist.

---

size

int size

The size of the sublist.

Constructor Detail

AbstractList.SubList

AbstractList.SubList(AbstractList backing,
                     int fromIndex,
                     int toIndex)

Construct the sublist.

Method Detail

checkMod

void checkMod()

This method checks the two modCount fields to ensure that there has not been a concurrent modification, returning if all is okay.

---

checkBoundsInclusive

private void checkBoundsInclusive(int index)

This method checks that a value is between 0 and size (inclusive). If it is not, an exception is thrown.

---

checkBoundsExclusive

private void checkBoundsExclusive(int index)

This method checks that a value is between 0 (inclusive) and size (exclusive). If it is not, an exception is thrown.

---

size

public int size()

Specified by AbstractList.subList to return the private field size.

Specified by:

size in interface List

Specified by:

size in class AbstractCollection

---

set

public java.lang.Object set(int index,
                            java.lang.Object o)

Specified by AbstractList.subList to delegate to the backing list.

Specified by:

set in interface List

Overrides:

set in class AbstractList

---

get

public java.lang.Object get(int index)

Specified by AbstractList.subList to delegate to the backing list.

Specified by:

get in interface List

Specified by:

get in class AbstractList

---

add

public void add(int index,
                java.lang.Object o)

Specified by AbstractList.subList to delegate to the backing list.

Specified by:

add in interface List

Overrides:

add in class AbstractList

---

remove

public java.lang.Object remove(int index)

Specified by AbstractList.subList to delegate to the backing list.

Specified by:

remove in interface List

Overrides:

remove in class AbstractList

---

removeRange

protected void removeRange(int fromIndex,
                           int toIndex)

Specified by AbstractList.subList to delegate to the backing list. This does no bounds checking, as it assumes it will only be called by trusted code like clear() which has already checked the bounds.

Overrides:

removeRange in class AbstractList

---

addAll

public boolean addAll(int index,
                      Collection c)

Specified by AbstractList.subList to delegate to the backing list.

Specified by:

addAll in interface List

Overrides:

addAll in class AbstractList

---

addAll

public boolean addAll(Collection c)

Specified by AbstractList.subList to return addAll(size, c).

Specified by:

addAll in interface List

Overrides:

addAll in class AbstractCollection

---

iterator

public Iterator iterator()

Specified by AbstractList.subList to return listIterator().

Specified by:

iterator in interface List

Overrides:

iterator in class AbstractList

---

listIterator

public ListIterator listIterator(int index)

Specified by AbstractList.subList to return a wrapper around the backing list's iterator.

Specified by:

listIterator in interface List

Overrides:

listIterator in class AbstractList
