All Implemented Interfaces:

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

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

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

characters

public void characters(java.lang.CharSequence chars,
              int 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 - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

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

comment

public void comment(java.lang.CharSequence chars,
           int 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 - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

properties - Additional information about the comment.

Throws:

XPathException

processingInstruction

public void processingInstruction(java.lang.String target,
                         java.lang.CharSequence data,
                         int 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 - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

properties - Additional information about the PI.

Throws:

XPathException

attribute

public void attribute(int nameCode,
             int typeCode,
             java.lang.CharSequence value,
             int locationId,
             int properties)
               throws XPathException

Description copied from class: ProxyReceiver

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:

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

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

value - the string value of the attribute

locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

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

DISABLE_ESCAPING

Disable escaping for this attribute

NO_SPECIAL_CHARACTERS

Attribute value contains no special characters

Throws:

XPathException

namespace

public void namespace(int namespaceCode,
             int properties)
               throws XPathException

Description copied from class: ProxyReceiver

Notify a namespace. Namespaces are notified after the startElement event, and before any children for the element. The namespaces that are reported are only required to include those that are different from the parent element; however, duplicates may be reported. A namespace must not conflict with any namespaces already used for element or attribute names.

Specified by:

namespace in interface Receiver

Overrides:

namespace in class ProxyReceiver

Parameters:

namespaceCode - an integer: the top half is a prefix code, the bottom half a URI code. These may be translated into an actual prefix and URI using the name pool. A prefix code of zero represents the empty prefix (that is, the default namespace). A URI code of zero represents a URI of "", that is, a namespace undeclaration.

properties - The most important property is REJECT_DUPLICATES. If this property is set, the namespace declaration will be rejected if it conflicts with a previous declaration of the same prefix. If the property is not set, the namespace declaration will be ignored if it conflicts with a previous declaration. This reflects the fact that when copying a tree, namespaces for child elements are emitted before the namespaces of their parent element. Unfortunately this conflicts with the XSLT rule for complex content construction, where the recovery action in the event of conflicts is to take the namespace that comes last. XSLT therefore doesn't recover from this error: it sets the REJECT_DUPLICATES flag, and this is treated as a hard error.

Throws:

XPathException

getMarkedNode

public NodeInfo getMarkedNode()

Description copied from class: BuilderMonitor

On completion of tree building, get the node that was marked using markNextNode().

Specified by:

getMarkedNode in class BuilderMonitor

Returns:

the marked node, or null if none was marked
