Class HTMLAugmentations

java.lang.Object

net.sourceforge.htmlunit.cyberneko.HTMLAugmentations

All Implemented Interfaces:

Augmentations

public class HTMLAugmentations
extends Object
implements Augmentations

This class is here to overcome the XNI changes to the Augmentations interface. In early versions of XNI, the augmentations interface contained a clear() method to remove all of the items from the augmentations instance. A later version of XNI changed this method to removeAllItems(). Therefore, this class extends the augmentations interface and explicitly implements both of these methods.

Note: This code is inspired by performance enhancements submitted by Marc-André Morissette.
