      • skip

        void skip​(long skipNum)
        Skip a number of elements in the iterator.
        Parameters:
        skipNum - the non-negative number of elements to skip
        Throws:
        java.util.NoSuchElementException - if skipped past the last element in the iterator.
      • getSize

        long getSize()
        Returns the total number of of items available through this iterator. For example, for some node N, N.getNodes().getSize() returns the number of child nodes of N visible through the current Session. In some implementations precise information about the number of elements may not be available. In such cases this method must return -1. API clients will then be able to use RangeIterator.getNumberRemaining to get an estimate on the number of elements.
        Returns:
        a long
      • getPosition

        long getPosition()
        Returns the current position within the iterator. The number returned is the 0-based index of the next element in the iterator, i.e. the one that will be returned on the subsequent next call.

        Note that this method does not check if there is a next element, i.e. an empty iterator will always return 0.

        Returns:
        a long
