Constructor Details

NodeListIterator

public NodeListIterator(List list)
Create a NodeListIterator.
Parameters:
list - the list, all of whose members must be instances of NodeInfo (this is not checked)

Method Details

atomize

public Value atomize()
            throws XPathException
Return the atomized value of the current node.
Specified by:
atomize in interface AxisIterator
Returns:
the atomized value.

getStringValue

public CharSequence getStringValue()
Return the string value of the current node.
Specified by:
getStringValue in interface AxisIterator
Returns:
the string value, as an instance of CharSequence.

iterateAxis

public AxisIterator iterateAxis(byte axis,
                                NodeTest test)
Return an iterator over an axis, starting at the current node.
Specified by:
iterateAxis in interface AxisIterator
Parameters:
axis - the axis to iterate over, using a constant such as Axis.CHILD
test - a predicate to apply to the nodes before returning them.

moveNext

public boolean moveNext()
Move to the next node, without returning it. Returns true if there is a next node, false if the end of the sequence has been reached. After calling this method, the current node may be retrieved using the current() function.
Specified by:
moveNext in interface AxisIterator
