      boolean optimizeScanForSingleObject()
      return true if we can save iterator creation and get a single entry
      Returns:
      true if we can optimize

    • freeSLHolder

      void freeSLHolder(IStoredListIterator<T> slh)
      Called by an outside scan that wants to quit the scan and return the slholder to the resource pool.
      Parameters:
      slh - Holder resource to return to pool; can be null.

    • remove

      void remove(IObjectInfo<T> oi)
      Remove an element described by ObjectInfo. [Tail] - .. - [beforeOi] - [oi] - [afterOi] - .. - [Head]
      Parameters:
      oi - an existing element between Tail and Head

    • removeUnlocked

      void removeUnlocked(IObjectInfo<T> oi)
      Remove an element described by ObjectInfo, while the SL is unlocked. [Tail] - .. - [beforeOi] - [oi] - [afterOi] - .. - [Head]
      Parameters:
      oi - an existing element between Tail and Head

    • addUnlocked

      IObjectInfo<T> addUnlocked(T subject)
      Store an element in the list, while the SL is unlocked . New elements are inserted at the tail.
      Parameters:
      subject - element to store.
      Returns:
      an information node representing the inserted element; null if StoredList has been invalidated.

    • invalidate

      boolean invalidate()
      Sets an indication that this StoredList is invalid. if isEmpty() returns true, the indication is set; otherwise the indication remains false. Called by PersistentGC when scanning for empty StoredList that can be garbage collected.
      Returns:
      true if StoredList was set to invalid; false otherwise.
