public AxisFilter(AxisIterator base,
                  java.util.function.Predicate<? super NodeInfo> 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
