Examples of org.milyn.delivery.sax.SAXElement

org.milyn.delivery.sax.SAXElement
Element details as described by the SAX even model API.
{@link org.milyn.delivery.sax.SAXVisitor} implementations will be passedan instance of this class for each of the event methods of {@link org.milyn.delivery.sax.SAXVisitor} implementations.
Element Writing/Serialization
Each SAXElement instance has a {@link Writer writer} set on it.{@link org.milyn.delivery.sax.SAXVisitor} implementations can take care ofserializing the elements at which they are targeted themselves. Alternatively, they can use the {@link org.milyn.delivery.sax.SAXElementWriterUtil} class.
{@link org.milyn.delivery.sax.SAXVisitor} implementations can also control the serializationof their "child elements" by {@link #setWriter(java.io.Writer,SAXVisitor) setting the writer}on the SAXElement instance they receive. This works because Smooks passes the writer instance that's set on a SAXElement instance to all of the SAXElement instances created for child elements.
Only one {@link SAXVisitor} can have access to the {@link java.io.Writer writer}for any individual {@link SAXElement}. The first visitor to request access to the writer via the {@link SAXElement#getWriter(SAXVisitor)} method "owns" the writerfor that element. Any other visitors requesting access to get or change the writer will result in a {@link SAXWriterAccessException} being thrown. In this situation,you need to restructure the offending Smooks configuration and eliminate one of the visitors attempting to gain access to the writer. If developing a new Visitor, you should annotate the new Visitor class with the {@link StreamResultWriter @StreamResultWriter}annotation. @author tom.fennelly@gmail.com
