Update a CzmlDataSource object by Server-sent Events

Hi,All,
I am going to update a CzmlDataSource by Server-sent Events. I go through the document about "EventSource and Streaming". But no code example is provided for how to update CzmlDataSource object when a SSEs comes. I read docs of CzmlDataSource, and guess call load() method of CzmlDataSource object when a SSEs update received. Am I right? Could anybody provide a simple example for me?

Thanks,
Shawn
