Constructor Summary

DelegatingEList.EListIterator()
Creates an instance.

DelegatingEList.EListIterator(int index)
Creates an instance advanced to the index.

Method Summary

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.
java.lang.Object	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(java.lang.Object 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

previous

public java.lang.Object previous()

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

Specified by:

previous in interface java.util.ListIterator

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

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

Returns:

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

set

public void set(java.lang.Object object)

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

Specified by:

set in interface java.util.ListIterator

Parameters:

object - the object to set.

Throws:

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(java.lang.Object object)

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

Specified by:

add in interface java.util.ListIterator

Parameters:

object - the object to add.
