Navigator.AxisFilter
public Navigator.AxisFilter(AxisIterator base,
NodeTest test)
- Construct a AxisFilter
- Parameters:
base
- the underlying iterator that returns all the nodes on
a required axis. This must not be an atomizing iterator!test
- a NodeTest that is applied to each node returned by the
underlying AxisIterator; only those nodes that pass the NodeTest are
returned by the AxisFilter
next
public NodeInfo next()
- Description copied from interface:
UnfailingIterator
- Get the next item in the sequence.
- Returns:
- the next Item. If there are no more nodes, return null.
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.
- Returns:
- a new iterator over the same sequence
