com.gargoylesoftware.htmlunit.javascript.host.html.HTMLCollection
An array of elements. Used for the element arrays returned by document.all, document.all.tags('x'), document.forms, window.frames, etc. Note that this class must not be used for collections that can be modified, for example map.areas and select.options.
This class (like all classes in this package) is specific for the JavaScript engine. Users of HtmlUnit shouldn't use it directly. @version $Revision: 5301 $ @author Daniel Gredler @author Marc Guillemot @author Chris Erskine @author Ahmed Ashour
