public class LinkedBuilderMonitor
extends BuilderMonitor

Monitor construction of a document tree. This allows a marker to be set during tree construction, in such a way that the node corresponding to the marker can be retrieved at the end of tree construction. This is used in the implementation of the XSLT 3.0 snapshot function.

public LinkedBuilderMonitor(LinkedTreeBuilder builder)

Method Detail

markNextNode

public void markNextNode(int nodeKind)

Description copied from class: BuilderMonitor

Indicate that the next node to be created will be of a given type, and request the monitor to remember the identity of this node.

Specified by:

markNextNode in class BuilderMonitor

Parameters:

nodeKind - the kind of node that will be created next. This will always be an element, text, comment, or processing-instruction node

startDocument

public void startDocument(int properties)
                   throws XPathException

Description copied from class: ProxyReceiver

Start of a document node.

Specified by:

startDocument in interface Receiver

Overrides:

startDocument in class ProxyReceiver

Parameters:

properties - bit-significant integer indicating properties of the document node. The definitions of the bits are in class ReceiverOption

Throws:

XPathException - if an error occurs

startElement

public void startElement(NodeName elemName,
                         SchemaType type,
                         AttributeMap attributes,
                         NamespaceMap namespaces,
                         Location location,
                         int properties)
                  throws XPathException

Description copied from class: ProxyReceiver

Notify the start of an element

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

elemName - the name of the element.

type - the type annotation of the element.

attributes - the attributes of this element

namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements

location - an object providing information about the module, line, and column where the node originated

properties - bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in class ReceiverOption

Throws:

XPathException - if an error occurs

characters

public void characters(java.lang.CharSequence chars,
                       Location locationId,
                       int properties)
                throws XPathException

Description copied from class: ProxyReceiver

Character data

Specified by:

characters in interface Receiver

Overrides:

characters in class ProxyReceiver

Parameters:

chars - The characters

locationId - provides information such as line number and system ID.

properties - Bit significant value. The following bits are defined:

DISABLE_ESCAPING

Disable escaping for this text node

USE_CDATA

Output as a CDATA section

Throws:

XPathException - if an error occurs

comment

public void comment(java.lang.CharSequence chars,
                    Location locationId,
