net.sf.molae.pipe.basic
Class ListBasedListIterator<E>

java.lang.Object
  net.sf.molae.pipe.basic.AbstractListIterator<E>
      net.sf.molae.pipe.basic.ListBasedListIterator<E>

All Implemented Interfaces:

Iterator<E>, ListIterator<E>

public class ListBasedListIterator<E>
extends AbstractListIterator<E>

Provides an implementation of the ListIterator interface that passes all calls to the underlying list. Parts are copied from AbstractList. Note that this implementation will throw an UnsupportedOperationException in response to its remove(), set(Object) and add(Object) methods unless the list's remove(int), set(int, Object), and add(int, Object) methods are implemented. This implementation can be made to throw runtime exceptions in the face of concurrent modification by providing a ModificationMark.

Constructor Summary

ListBasedListIterator(List<E> base)
Constructs a ListBasedListIterator object.

ListBasedListIterator(List<E> base, int index)
Constructs a ListBasedListIterator object.

ListBasedListIterator(List<E> base, int index, ModificationMark mark)
Constructs a ListBasedListIterator object.

ListBasedListIterator(List<E> base, ModificationMark mark)
Constructs a ListBasedListIterator object.

Method Summary

void	add(E o) This implementation calls the corresponding method of the base list.
protected E	get() This implementation calls the corresponding method of the base list.
boolean	hasNext() This implementation compares the cursor with the size of the base list.
void	remove() This implementation calls the corresponding method of the base list.
void	set(E o) This implementation calls the corresponding method of the base list.

Constructs a ListBasedListIterator object.

Parameters:

base - the base list

ListBasedListIterator

public ListBasedListIterator(List<E> base,
                             int index,
                             ModificationMark mark)

Constructs a ListBasedListIterator object.

Parameters:

base - the base list

index - start position of the created ListIterator.

Method Detail

hasNext

public boolean hasNext()

This implementation compares the cursor with the size of the base list.

Specified by:

hasNext in interface Iterator<E>

Specified by:

hasNext in interface ListIterator<E>

Specified by:

hasNext in class AbstractListIterator<E>

get

protected E get()

This implementation calls the corresponding method of the base list.

Overrides:

get in class AbstractListIterator<E>

Returns:

object of base list at current cursor position.

Throws:

ConcurrentModificationException - if modification marks are not equal

remove

public void remove()

This implementation calls the corresponding method of the base list.

Specified by:

remove in interface Iterator<E>

Specified by:

remove in interface ListIterator<E>

Overrides:

remove in class AbstractListIterator<E>

Throws:

IllegalStateException - depending on the base list

set

public void set(E o)

This implementation calls the corresponding method of the base list.

Specified by:

set in interface ListIterator<E>

Overrides:

set in class AbstractListIterator<E>

Throws:

ClassCastException - depending on the base list

IllegalArgumentException - depending on the base list

IllegalStateException - depending on the base list

add

public void add(E o)

This implementation calls the corresponding method of the base list.

Specified by:

add in interface ListIterator<E>

Overrides:

add in class AbstractListIterator<E>

Throws:

ClassCastException - depending on the base list

IllegalArgumentException - depending on the base list
