    • makeReadOnlyCopy

      public void makeReadOnlyCopy()
      Called by index when about to make an update
      Specified by:
      makeReadOnlyCopy in interface CopyOnWriteIndexPart<T extends FeatureStructure>

    • find

      public int find(T obj)
      Parameters:
      obj - the object to find in the table (if it is there)
      Returns:
      the position of obj in the table, or -1 if not in the table

    • get

      public T get(int index)
      For iterator use
      Parameters:
      index - a magic number returned by the internal find
      Returns:
      the T at that spot, or null if nothing there

    • moveToNextFilled

      public int moveToNextFilled(int pos)
      advance pos until it points to a non 0 or is 1 past end
      Parameters:
      pos - -
      Returns:
      updated pos

    • moveToPreviousFilled

      public int moveToPreviousFilled(int pos)
      decrement pos until it points to a non 0 or is -1
      Parameters:
      pos - -
      Returns:
      updated pos

    • iterator

      public Iterator<T> iterator()
      Specified by:
      iterator in interface CopyOnWriteIndexPart<T extends FeatureStructure>
      Returns:
      iterator over all the elements

    • moveTo

      public int moveTo(FeatureStructure fs)
      if the fs is in the set, the iterator should return it. if not, return -1 (makes iterator invalid)
      Parameters:
      fs - position to this fs
      Returns:
      the index if present, otherwise -1;

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • getCapacity

      public int getCapacity()
      Returns:
      the capacity >= size

      Specified by:
      isOriginal in interface CopyOnWriteIndexPart<T extends FeatureStructure>
      Returns:
      true if this cow version is the same as the original. true means the index has not been updated
