Constructor Detail

FollowingEnumeration

public 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 AxisIterator getAnother()

Description copied from interface: UnfailingIterator

Get another iterator over the same sequence of items, positioned at the start of the sequence. It must be possible to call this method at any time, whether none, some, or all of the items in the original iterator have been read. The method is non-destructive: it does not change the state of the original iterator.

Specified by:

getAnother in interface SequenceIterator

Specified by:

getAnother in interface AxisIterator

Specified by:

getAnother in interface UnfailingIterator

Specified by:

getAnother in class Navigator.BaseEnumeration

Returns:

a new iterator over the same sequence
