Field Detail

current

protected AbstractLinkedList.Node 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. 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 java.util.ConcurrentModificationException may be thrown by the operations.

protected AbstractLinkedList.Node next

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