Class HistoricalVector<E>

  • Type Parameters:
    E - element type
    All Implemented Interfaces:
    Iterable<E>, Collection<E>, List<E>, HistoricalCollection<E>, HistoricalList<E>, HistoryManager.HistoricalElement
    public class HistoricalVector<E>
extends AbstractHistoricalList<E,​Vector<E>>
    Vector-valued historical state. The current vector is always maintained, and past states of the vector are obtained by applying the events between now and the requested time in reverse.

    This class does not implement all Vector methods, but only those shared with List. The returned argument is however a List.

    The Iterator returned by this class does not support the remove(), add() and set() methods. Any returned sublist is unmodifiable.
