  java.util.AbstractList.Itr

All Implemented Interfaces:

Iterator

Direct Known Subclasses:

AbstractList.ListItr

Enclosing class:

AbstractList

private class AbstractList.Itr

extends Object

implements Iterator

Field Summary

(package private) int	cursor Index of element to be returned by subsequent call to next.
(package private) int	expectedModCount The modCount value that the iterator believes that the backing List should have.
(package private) int	lastRet Index of element returned by most recent call to next or previous.

Constructor Summary

private

AbstractList.Itr()

Method Summary

(package private) void	checkForComodification()
boolean	hasNext() Returns true if the iteration has more elements.
Object	next() Returns the next element in the iteration.
void	remove() Removes from the underlying collection the last element returned by the iterator (optional operation).

Field Detail

cursor

int cursor

Index of element to be returned by subsequent call to next.

lastRet

int lastRet

Index of element returned by most recent call to next or previous. Reset to -1 if this element is deleted by a call to remove.

expectedModCount

int expectedModCount

The modCount value that the iterator believes that the backing List should have. If this expectation is violated, the iterator has detected concurrent modification.

Method Detail

hasNext

public boolean hasNext()

Description copied from interface: Iterator

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator

Returns:

true if the iterator has more elements.

next

public Object next()

Description copied from interface: Iterator

Returns the next element in the iteration.

Specified by:

next in interface Iterator

Returns:

the next element in the iteration.

remove

public void remove()

Description copied from interface: Iterator

Removes from the underlying collection the last element returned by the iterator (optional operation). This method can be called only once per call to next. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

Specified by:

remove in interface Iterator

checkForComodification

final void checkForComodification()
