EmptyTextFilter
public EmptyTextFilter(AxisIterator base)
Construct an EmptyTextFilter- Parameters:
base
- the underlying iterator that returns all the nodes on a required axis. This must not be an atomizing iterator

Method Detail
-
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:
