Method Summary

void	add(E1 object) Adds the object at the next index and advances the iterator past it.
protected void	doAdd(E object) Adds the object at the next index and advances the iterator past it.
protected E	doPrevious() Returns the previous object and advances the iterator.
protected void	doSet(E object) Sets the object at the index of the last call to next or previous.
boolean	hasPrevious() Returns whether there are more objects for previous().
int	nextIndex() Returns the index of the object that would be returned by calling next.
E1	previous() Returns the previous object and advances the iterator.
int	previousIndex() Returns the index of the object that would be returned by calling previous.
void	set(E1 object) Sets the object at the index of the last call to next or previous.

Constructor Detail

DelegatingEList.EListIterator

public DelegatingEList.EListIterator()

Creates an instance.

DelegatingEList.EListIterator

public DelegatingEList.EListIterator(int index)

Creates an instance advanced to the index.

Parameters:

index - the starting index.

Method Detail

hasPrevious

public boolean hasPrevious()

Returns whether there are more objects for previous(). Returns whether there are more objects.

Specified by:

hasPrevious in interface java.util.ListIterator<E1>

previous

public E1 previous()

Returns the previous object and advances the iterator. This implementation delegates to doPrevious.

Specified by:

previous in interface java.util.ListIterator<E1>

Returns:

the previous object.

Throws:

java.util.NoSuchElementException - if the iterator is done.

doPrevious

protected E doPrevious()

Returns the previous object and advances the iterator. This implementation delegates to get.

Returns:

the previous object.

Throws:

java.util.NoSuchElementException - if the iterator is done.

nextIndex

public int nextIndex()

Returns the index of the object that would be returned by calling next.

Specified by:

nextIndex in interface java.util.ListIterator<E1>

Returns:

the index of the object that would be returned by calling next.

previousIndex

public int previousIndex()

Returns the index of the object that would be returned by calling previous.

Specified by:

previousIndex in interface java.util.ListIterator<E1>

Returns:

the index of the object that would be returned by calling previous.

set

public void set(E1 object)

Sets the object at the index of the last call to next or previous. This implementation delegates to doSet.

Specified by:

set in interface java.util.ListIterator<E1>

Parameters:

object - the object to set.

Throws:

java.lang.IllegalStateException - if next or previous have not yet been called, or remove or add have already been called after the last call to next or previous.

doSet

protected void doSet(E object)

Sets the object at the index of the last call to next or previous. This implementation delegates to set.

Parameters:

object - the object to set.

Throws:

java.lang.IllegalStateException - if next or previous have not yet been called, or remove or add have already been called after the last call to next or previous.

add

public void add(E1 object)

Adds the object at the next index and advances the iterator past it. This implementation delegates to doAdd.

Specified by:

add in interface java.util.ListIterator<E1>

Parameters:

object - the object to add.

doAdd

protected void doAdd(E object)

Adds the object at the next index and advances the iterator past it. This implementation delegates to add(int, Object).

Parameters:

object - the object to add.
