    boolean
    hasNext()
    Returns true if the iterator can be advanced past its current location.

    moveToNextIndex()
    Sets the internal index so that the `next' object can be returned.
    int
    next()
    Advances the iterator to the next element in the underlying collection and returns it.
    protected final int

  • Field Details

    • _expectedSize

      protected int _expectedSize
      the number of elements this iterator believes are in the data structure it accesses.

    • _index

      protected int _index
      the index used for iteration.

  • Constructor Details

    • TIntIterator

      public TIntIterator(TIntHash hash)
      Creates a TIntIterator for the elements in the specified collection.

  • Method Details

    • next

      public int next()
      Advances the iterator to the next element in the underlying collection and returns it.
      Returns:
      the next int in the collection

    • nextIndex

      protected final int nextIndex()
      Returns the index of the next value in the data structure or a negative value if the iterator is exhausted.
      Returns:
      an int value
      Throws:
      ConcurrentModificationException - if the underlying collection's size has been modified since the iterator was created.

    • hasNext

      public boolean hasNext()
      Returns true if the iterator can be advanced past its current location.
      Returns:
      a boolean value

    • remove

      public void remove()
      Removes the last entry returned by the iterator. Invoking this method more than once for a single entry will leave the underlying data structure in a confused state.

    • moveToNextIndex

      protected final void moveToNextIndex()
      Sets the internal index so that the `next' object can be returned.
