org.waveprotocol.wave.client.common.safehtml.SafeHtmlBuilder

A builder that facilitates the building up of XSS-safe HTML from text snippets. It is used essentially like a {@link StringBuilder}; unlike a {@link StringBuilder}, it automatically HTML-escapes appended input where necessary.

In addition, it supports methods that allow strings with HTML markup to be appended without escaping: One can append other {@link SafeHtml} objects, andone can append constant strings. The method that appends constant strings ( {@link #appendHtmlConstant(String)}) requires a convention of use to be adhered to in order for this class to adhere to the contract required by {@link SafeHtml}.

The accumulated XSS-safe HTML can be obtained in the form of a {@link SafeHtml} via the {@link #toSafeHtml()} method.

This class is not thread-safe.

      // Also, this code could potentially be put behind a runAsync boundary, to
      // save whatever dependencies it uses from the initial download.
      new Timer() {
        @Override
        public void run() {
          SafeHtmlBuilder stack = new SafeHtmlBuilder();


          Throwable error = t;
          while (error != null) {
            String token = String.valueOf((new Date()).getTime());
            stack.appendHtmlConstant("Token:  " + token + "<br> ");
            stack.appendEscaped(String.valueOf(error.getMessage())).appendHtmlConstant("<br>");
            for (StackTraceElement elt : error.getStackTrace()) {
              stack.appendHtmlConstant("  ")
                  .appendEscaped(maybe(elt.getClassName(), "??")).appendHtmlConstant(".") //
                  .appendEscaped(maybe(elt.getMethodName(), "??")).appendHtmlConstant(" (") //
                  .appendEscaped(maybe(elt.getFileName(), "??")).appendHtmlConstant(":") //
                  .appendEscaped(maybe(elt.getLineNumber(), "??")).appendHtmlConstant(")") //
                  .appendHtmlConstant("<br>");
            }
            error = error.getCause();
            if (error != null) {
              stack.appendHtmlConstant("Caused by: ");
            }
          }


          whenReady.use(stack.toSafeHtml());
        }
      }.schedule(1);
    }
