Constructor Detail

AxisFilter

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

Method Detail

next

public NodeInfo next()

Description copied from interface: UnfailingIterator

Specified by:

next in interface SequenceIterator

Specified by:

next in interface AxisIterator

Specified by:

next in interface UnfailingIterator

Returns:

the next Item. If there are no more items, return null.
