Examples of javax.servlet.jsp.tagext.JspFragment.invoke()

javax.servlet.jsp.tagext.JspFragment.invoke()
Executes the fragment and directs all output to the given Writer, or the JspWriter returned by the getOut() method of the JspContext associated with the fragment if out is null. @param out The Writer to output the fragment to, or null if output should be sent to JspContext.getOut(). @throws javax.servlet.jsp.JspException Thrown if an error occuredwhile invoking this fragment. @throws javax.servlet.jsp.SkipPageException Thrown if the pagethat (either directly or indirectly) invoked the tag handler that invoked this fragment is to cease evaluation. The container must throw this exception if a Classic Tag EventHandler returned Tag.SKIP_PAGE or if a Simple Tag EventHandler threw SkipPageException. @throws java.io.IOException If there was an error writing to the stream.

                   allow sub-tags to do work during START before rendering
                   this makes it possible to have tags out of order and to
                   have rendering work correctly
