字段详细资料

parent

protected final AbstractLinkedList<E> parent

The parent list

next

protected AbstractLinkedList.Node<E> next

The node that will be returned by next(). If this is equal to AbstractLinkedList.header then there are no more values to return.

nextIndex

protected int nextIndex

The index of next.

current

protected AbstractLinkedList.Node<E> current

The last node that was returned by next() or previous(). Set to null if next() or previous() haven't been called, or if the node has been removed with remove() or a new node added with add(Object). Should be accessed through getLastNodeReturned() to enforce this behaviour.

expectedModCount

protected int expectedModCount

The modification count that the list is expected to have. If the list doesn't have this count, then a ConcurrentModificationException may be thrown by the operations.

构造器详细资料

LinkedListIterator

protected LinkedListIterator(AbstractLinkedList<E> parent,
                             int fromIndex)
                      throws IndexOutOfBoundsException

Create a ListIterator for a list.

参数:

parent - the parent list

fromIndex - the index to start at

抛出:

IndexOutOfBoundsException - if fromIndex is less than 0 or greater than the size of the list

方法详细资料

checkModCount

protected void checkModCount()

Checks the modification count of the list is the value that this object expects.

抛出:

ConcurrentModificationException - If the list's modification count isn't the value that was expected.

getLastNodeReturned

protected AbstractLinkedList.Node<E> getLastNodeReturned()
                                                  throws IllegalStateException

Gets the last node returned.

返回:

the last node returned

抛出:

IllegalStateException - If next() or previous() haven't been called, or if the node has been removed with remove() or a new node added with add(Object).
