Examples of org.openqa.jetty.html.Page

org.openqa.jetty.html.Page
HTML Page. A HTML Page extends composite with the addition of the HTML Header tags, fields and elements. Furthermore, individual parts of the page may be written or the progressive page be output with flush.
Pages contain parameters and named sections. These are used by derived Page classes that implement a Look and Feel. Page users may add to name sections such as "Margin" or "Footer" and set parameters such as "HelpUrl" without knowledge of how the look and feel will arrange these. To assist with standard look and feel creation Page defines a set of standard names for many common parameters and sections.
If named sections are used, the page constructor or completeSections must add the named section to the page in the appropriate places. If named sections are not added to the page, then they can only be written with an explicit call to write(out,"section",end); Changes in behaviour to section creation and adding, should be controlled via page properties.
