public class LinkedBuilderMonitor
extends BuilderMonitor

Monitor construction of a TinyTree. 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.

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

markAttributeNode

public void markAttributeNode(NodeInfo origin)

Description copied from class: BuilderMonitor

Indicate that the most recently written attribute whose name matches that of the supplied node is to act as the marked node

Specified by:

markAttributeNode in class BuilderMonitor

Parameters:

origin - the attribute in the input corresponding to the marked node in the output

markNamespaceNode

public void markNamespaceNode(NodeInfo origin)

Description copied from class: BuilderMonitor

Indicate that the most recently written attribute whose name matches that of the supplied node is to act as the marked node

Specified by:

markNamespaceNode in class BuilderMonitor

Parameters:

origin - the attribute in the input corresponding to the marked node in the output

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 ReceiverOptions

Throws:

XPathException - if an error occurs

startContent

public void startContent()
                  throws XPathException

Description copied from class: ProxyReceiver

Notify the start of the content, that is, the completion of all attributes and namespaces. Note that the initial receiver of output from XSLT instructions will not receive this event, it has to detect it itself. Note that this event is reported for every element even if it has no attributes, no namespaces, and no content.

Specified by:

startContent in interface Receiver

Overrides:

startContent in class ProxyReceiver

Throws:

XPathException - if an error occurs

characters

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

Description copied from class: ProxyReceiver

Output a comment

Specified by:

comment in interface Receiver

Overrides:

comment in class ProxyReceiver

Parameters:

chars - The content of the comment

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

properties - Additional information about the comment.

Throws:

XPathException - if an error occurs

processingInstruction

public void processingInstruction(String target,
                         CharSequence data,
                         Location locationId,
                         int properties)
                           throws XPathException

Description copied from class: ProxyReceiver

Processing Instruction

Specified by:

processingInstruction in interface Receiver

Overrides:

processingInstruction in class ProxyReceiver

Parameters:

target - The PI name. This must be a legal name (it will not be checked).

data - The data portion of the processing instruction

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

properties - Additional information about the PI.

Throws:

XPathException - if an error occurs

attribute

public void attribute(NodeName name,
             SimpleType typeCode,
             CharSequence value,
             Location locationId,
             int properties)
               throws XPathException

Notify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.

Specified by:

attribute in interface Receiver

Overrides:

attribute in class ProxyReceiver

Parameters:

name - The name of the attribute, as held in the name pool

NO_SPECIAL_CHARACTERS

Attribute value contains no special characters

@throws IllegalStateException: attempt to output an attribute when there is no open element start tag

Throws:

namespace

public void namespace(NamespaceBinding namespaceBinding,
             int properties)
               throws XPathException
