<Method name="GetJSONString">
<Description><![CDATA[
Returns the contents of the proxy object to the current device in JSON format.<br/>
This method is called when a proxy object is used in conjunction with
the <class>%ZEN.Auxiliary.jsonProvider</class> component.<br/>
<var>format</var> is a flags string to control output formatting options.<br/>
The following character option codes are supported:<br/>
1-9 : indent with this number of spaces (4 is the default with the 'i' format specifier)<br/>
a - output null arrays/objects<br/>
b - line break before opening { of objects<br/>
c - output the Caché-specific "_class" and "_id" properties (if a child property is an instance of a concrete object class)<br/>
e - output empty object properties<br/>
i - indent with 4 spaces unless 't' or 1-9<br/>
l - output empty lists<br/>
n - newline (lf)<br/>
o - output empty arrays/objects<br/>
q - output numeric values unquoted even when they come from a non-numeric property<br/>
s - use strict JSON output - <strong>NOTE:</strong> special care should be taken when sending data to a browser, as using this flag
may expose you to cross site scripting (XSS) vulnerabilities if the data is sent inside <code><script></code> tags. Zen uses
this technique extensively, so this flag should <strong>NOT</strong> be specified for jsonProviders in Zen pages.<br/>
t - indent with tab character<br/>
u - output pre-converted to UTF-8 instead of in native internal format<br/>
w - Windows-style cr/lf newline<br/>]]></Description>
