Class MarkupElement

  • Direct Known Subclasses:
    ComponentTag, HtmlSpecialTag, RawMarkup
    public abstract class MarkupElement
extends java.lang.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.
