Constructor Detail

### Navigator.FollowingEnumeration

    public Navigator.FollowingEnumeration(NodeInfo start)

  Create an iterator over the "following" axis

  Parameters:
    `start` - the initial context node

Method Detail

### advance

    public void advance()

  Description copied from class: `Navigator.BaseEnumeration`
  The advance() method must be provided in each concrete implementation. It must leave the variable current set to the next node to be returned in the iteration, or to null if there are no more nodes to be returned.

  Specified by:
    `advance` in class `Navigator.BaseEnumeration`

### getAnother

    public SequenceIterator getAnother()

  Description copied from interface: `SequenceIterator`
  Get another SequenceIterator that iterates over the same items as the original, but which is repositioned at the start of the sequence.

  This method allows access to all the items in the sequence without disturbing the current position of the iterator. Internally, its main use is in evaluating the last() function.

  This method does not change the state of the iterator.

  Specified by:
    `getAnother` in interface `SequenceIterator`
  Specified by:
    `getAnother` in interface `UnfailingIterator`
  Specified by:
    `getAnother` in class `Navigator.BaseEnumeration`
  Returns:
    a SequenceIterator that iterates over the same items, positioned before the first item
