com.saxonica.stream.om.FleetingNode

com.saxonica.stream.om.FleetingParentNode

All Implemented Interfaces:

Source, PullEvent, Item, NodeInfo, Sequence

Direct Known Subclasses:

FleetingDocumentNode, FleetingElementNode

public abstract class FleetingParentNode
extends FleetingNode

A streamed document or element node. This abstract class maintains information about the number of child nodes that have been read, broken down by node kind and node name, so that positional preducates can be supported in patterns and child selections

Method Detail

incrementChildCount

public void incrementChildCount(int nodeKind,
                       NodeName name)

getPosition

public int getPosition(NodeTest nodeTest)
                throws XPathException

Get the position of the last child node encountered. This method must be called AFTER incrementChildCount has been called in respect of that child.

Parameters:

nodeTest - filters the nodes to be counted

Returns:

the number of previous siblings (plus the current node) that match the node test

Throws:

XPathException - for an unsupported kind of NodeTest
