AxisFilter
S 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

Method Details

next
Description copied from interface:AxisIterator
Get the next item in the sequence.- Returns:
- the next Item. If there are no more nodes, return null.
-
getAnother
Description copied from interface:AxisIterator
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
