toHtml

public void toHtml(E4StringBufferHtml buf,
                   E4ServletImplementation_Intf servlet)
            throws java.lang.Exception

Description copied from interface: E4HtmlElement_Intf

Create the HTML output for this element. Also run throught all child elements, and call their E4HtmlElement_Intf.toHtml(e4s.util.E4StringBufferHtml, e4s.servlet.E4ServletImplementation_Intf) function to generate output of those objects which becomes appended. Normally, there is no need to call this function anyway, and this also might result in side effects of too-early relasing of objects in some cases. This function is called by E4ServletImplementation_Intf.write(e4s.html.E4HtmlElement) on the top level HTML element (common this is a HTML or BODY element) and branches down to all child elements.

Specified by:
