Question:
To simplify the creation of WML code a so called presentation factory can be used, which defines methods that create the code. A presentation factory defines the following method. A client calls this method, providing "true" for the boolean newcontext. What does he achive by that? public static String openNewCard(String id, String title, boolean newcontext) { StringBuffer ret = new StringBuffer(); ret.append("<card id=\""); ret.append(id); ret.append("\" title=\""); ret.append(title); ret.append("\" newcontext=\""); ret.append(newcontext); ret.append("\">"); return ret.toString(); }

Prior to opening the card the following WMLScript has been run:
WMLBrowser.setVar("greeting", "hello");
After opening the card this value can still be retrieved using
var greeting = WMLBrowser.getVar("greeting");

It is a common way to avoid fragments of the previous site to be visible
in the site.

He avoids a potential security risk: Other sites could read the values
of variables if newcontext were set to "false".

The browser will clean its cache.

The browser will clean its WMLScript variables.

The browser will clean its old link values.
