  net.sf.saxon.event.SequenceReceiver
      net.sf.saxon.event.ProxyReceiver

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().

Method Detail

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

getMarkedNode

public abstract NodeInfo getMarkedNode()
