Examples of org.apache.wicket.markup.ComponentTag

org.apache.wicket.markup.ComponentTag
A subclass of MarkupElement which represents a "significant" markup tag, such as a component open tag. Insignificant markup tags (those which are merely concerned with markup formatting operations and do not denote components or component nesting) are coalesced into instances of RawMarkup (also a subclass of MarkupElement). @author Jonathan Locke
