ResponseDataHandler (The ZK Charts library 11.4.7.0 API)

java.lang.Object
- org.zkoss.chart.util.ResponseDataHandler

All Implemented Interfaces:

org.zkoss.json.JSONAware
```
public class ResponseDataHandler
extends Object
implements org.zkoss.json.JSONAware
```
A response data handler for Charts's smart update changes. The handler can merge the duplicated data changes and ignore the changes if they are unnecessary. For example add a new series with multiple points that the addPoint command changes are unnecessary in this case. This handler is used when the component is going to output the data in JSON string at rendering phase, so it is a good timing to merge the response data there.
