Class BuilderMonitor

java.lang.Object

net.sf.saxon.event.SequenceReceiver

All Implemented Interfaces:

Result, Receiver

Direct Known Subclasses:

LinkedBuilderMonitor, TinyBuilderMonitor

public abstract class BuilderMonitor
extends ProxyReceiver

A BuilderMonitor can be inserted into a pipeline immediately in front of a Builder. During tree construction, the method markNextNode() can be called to request that the next node to be created is treated specially by remembering the current position on the tree; on completion of the tree construction, the method getMarkedNode() can be called to return the NodeInfo that was created immediately after calling markNextNode().

BuilderMonitor

public BuilderMonitor(Receiver next)

Method Details

markNextNode

public abstract void markNextNode(int nodeKind)

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.

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 abstract void markAttributeNode(NodeInfo origin)

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

Parameters:

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

markNamespaceNode

public abstract void markNamespaceNode(NodeInfo origin)

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

Parameters:

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

getMarkedNode

public abstract NodeInfo getMarkedNode()

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

Returns:

the marked node, or null if none was marked
