Class MarkupElement

java.lang.Object

org.apache.wicket.markup.MarkupElement

Direct Known Subclasses:

ComponentTag, HtmlSpecialTag, RawMarkup

public abstract class MarkupElement
extends Object

Base class for different kinds of markup elements. Markup elements are held in a Markup container object.

Wicket divides markup like (x)html, wml etc. into two types of MarkupElements:

• ComponentTag, which represents a "significant" markup tag (meaning that the tag has some meaning to Wicket)
• RawMarkup, which is a section of unparsed markup having no meaning to Wicket.
