The au-decoder-class Element

Syntax:

<au-decoder-class>a_class_name</au-decoder-class>

[Default: null (using the default JSON-based format)]

Since 5.0.4

It specifies which class will be used to implement the AU decoder. The AU decoder is used to decode the AU requests. The class must implement AuDecoder.

By default, the AU request is sent in the JSON format. If you prefer to use another format, you could provide an implementation as follows.

1. Implement AuDecoder. You can reference the default implementation, inner class AuDecoder in org.zkoss.zk.au.http.DHtmlUpdateServlet.
2. Register it by specifying it with the au-decoder-class element in WEB-INF/zk.xml
3. Override a JavaScript method called zAu.encode(int, Event, Desktop) to encode to the custom format
