Class TLinkedList.IteratorImpl

java.lang.Object
  gnu.trove.list.linked.TLinkedList.IteratorImpl

All Implemented Interfaces:

java.util.Iterator<T>, java.util.ListIterator<T>

Enclosing class:

TLinkedList<T extends TLinkable<T>>

protected final class TLinkedList.IteratorImpl
extends java.lang.Object
implements java.util.ListIterator<T>

A ListIterator that supports additions and deletions.

Method Summary

void	add(T linkable) Insert linkable at the current position of the iterator.
boolean	hasNext() True if a call to next() will return an object.
boolean	hasPrevious() True if a call to previous() will return a value.
T	next() Returns the value at the Iterator's index and advances the iterator.
int	nextIndex() returns the index of the next node in the list (the one that would be returned by a call to next()).
T	previous() Returns the value before the Iterator's index and moves the iterator back one index.
int	previousIndex() Returns the previous element's index.
void	remove() Removes the current element in the list and shrinks its size accordingly.
void	set(T linkable) Replaces the current element in the list with linkable

Method Detail

add

public final void add(T linkable)

Insert linkable at the current position of the iterator. Calling next() after add() will return the added object.

Specified by:

add in interface java.util.ListIterator<T extends TLinkable<T>>

Parameters:

linkable - an object of type TLinkable

hasNext

public final boolean hasNext()

True if a call to next() will return an object.

Specified by:

hasNext in interface java.util.Iterator<T extends TLinkable<T>>

Specified by:

hasNext in interface java.util.ListIterator<T extends TLinkable<T>>

Returns:

a boolean value

hasPrevious

public final boolean hasPrevious()

True if a call to previous() will return a value.

Specified by:

hasPrevious in interface java.util.ListIterator<T extends TLinkable<T>>

Returns:

a boolean value

next

public final T next()

Returns the value at the Iterator's index and advances the iterator.

Specified by:

next in interface java.util.Iterator<T extends TLinkable<T>>

Specified by:

next in interface java.util.ListIterator<T extends TLinkable<T>>

Returns:

an Object value

Throws:

java.util.NoSuchElementException - if there is no next element

nextIndex

public final int nextIndex()

returns the index of the next node in the list (the one that would be returned by a call to next()).

Specified by:

nextIndex in interface java.util.ListIterator<T extends TLinkable<T>>

Returns:

an int value

previous

public final T previous()

Returns the value before the Iterator's index and moves the iterator back one index.

Specified by:

previous in interface java.util.ListIterator<T extends TLinkable<T>>

Returns:

an Object value

Throws:

java.util.NoSuchElementException - if there is no previous element.

previousIndex

public final int previousIndex()

Returns the previous element's index.

Specified by:

previousIndex in interface java.util.ListIterator<T extends TLinkable<T>>

Returns:

an int value

remove

public final void remove()

Removes the current element in the list and shrinks its size accordingly.

Specified by:

remove in interface java.util.Iterator<T extends TLinkable<T>>

Specified by:

remove in interface java.util.ListIterator<T extends TLinkable<T>>

Throws:

java.lang.IllegalStateException - neither next nor previous have been invoked, or remove or add have been invoked after the last invocation of next or previous.

set

public final void set(T linkable)

Replaces the current element in the list with linkable

Specified by:

set in interface java.util.ListIterator<T extends TLinkable<T>>

Parameters:

linkable - an object of type TLinkable
