org.apache.wicket.markup.parser.filter
Class HtmlHeaderSectionHandler

java.lang.Object
  org.apache.wicket.markup.parser.AbstractMarkupFilter
      org.apache.wicket.markup.parser.filter.HtmlHeaderSectionHandler

All Implemented Interfaces:: IMarkupFilter

public final class HtmlHeaderSectionHandler
extends AbstractMarkupFilter
extends AbstractMarkupFilter

This is a markup inline filter.

It assumes that WicketTagIdentifier has been called first and search for a <head> tag (note: not wicket:head). Provided the markup contains a <body> tag it will automatically prepend a <head> tag if missing.

Additionally this filter handles <wicket:header-items/>. If there is such tag then it is marked as the one that should be used as HtmlHeaderContainer, by setting its id to "_header_".

Note: This handler is only relevant for Pages (see MarkupParser.newFilterChain())
