Class ElementHandlerBase

java.lang.Object

com.icl.saxon.handlers.ElementHandler

com.icl.saxon.handlers.ElementHandlerBase

All Implemented Interfaces:

NodeHandler

public class ElementHandlerBase
extends ElementHandler

This class is the default element handler from which user-defined element handlers can inherit. It is provided for convenience: use is optional. The individual methods of the default element handler do nothing with the content; in a subclass it is therefore only necessary to implement those methods that need to do something specific.

The startElement() method calls applyTemplates(), so child elements will always be processed.
