Class AbstractDOMOutputProcessor

org.jdom2.output.support.AbstractOutputProcessor

org.jdom2.output.support.AbstractDOMOutputProcessor

All Implemented Interfaces:

DOMOutputProcessor

public abstract class AbstractDOMOutputProcessor
extends AbstractOutputProcessor
implements DOMOutputProcessor

This class provides a concrete implementation of DOMOutputProcessor for supporting the DOMOutputter.

Overview

This class is marked abstract even though all methods are fully implemented. The process*(...) methods are public because they match the DOMOutputProcessor interface but the remaining methods are all protected.

People who want to create a custom DOMOutputProcessor for DOMOutputter are able to extend this class and modify any functionality they want. Before sub-classing this you should first check to see if the Format class can get you the results you want.

Subclasses of this should have reentrant methods. This is easiest to accomplish simply by not allowing any instance fields. If your sub-class has an instance field/variable, then it's probably broken.

The Stacks

One significant feature of this implementation is that it creates and maintains both a NamespaceStack and FormatStack that are managed in the printElement(FormatStack, NamespaceStack, org.w3c.dom.Document, Element) method. The stacks are pushed and popped in that method only. They significantly improve the performance and readability of the code.

The NamespaceStack is only sent through to the printElement(FormatStack, NamespaceStack, org.w3c.dom.Document, Element) and printContent(FormatStack, NamespaceStack, org.w3c.dom.Document, org.w3c.dom.Node, Walker) methods, but the FormatStack is pushed through to all print* Methods.

Content Processing

This class delegates the formatting of the content to the Walker classes and you can create your own custom walker by overriding the AbstractOutputProcessor.buildWalker(FormatStack, List, boolean) method.
