Interface NodeHandler

All Known Implementing Classes:

DefaultNodeHandler

public interface NodeHandler

Objects implementing the NodeHandler interface should be capable of translating an XML DOM object tree into an analogous hierarchy of application objects, in a similar manner to DefaultNodeHandler. A DefaultNodeHandler is capable of 'delegating' the processing of parts of its DOM tree to any other object implementing this NodeHandler interface.

Method Summary

void	processNode(org.w3c.dom.Node n, java.lang.Object o) Recursively processes all the children of a given XML node in the context of an application object represented by that node, in order to populate the application object and create and populate other 'child' application objects.

Method Detail

processNode

public void processNode(org.w3c.dom.Node n,
                        java.lang.Object o)
                 throws NodeHandlerException

Recursively processes all the children of a given XML node in the context of an application object represented by that node, in order to populate the application object and create and populate other 'child' application objects.

Parameters:

n - current node whose children will be processed to populate the context application object.

o - the context application object.

Throws:

NodeHandlerException - if unable to instantiate a child object or handler object, find a method corresponding to a simple element, or an exception occurs while calling a method on a child object.
