Single data provider and multiple data sources
Hi,
I'd like to know if using a single data adapter to handle multiple data sources is the correct approach. The more I think of it, the more I believe it's not. Thing is, each of the data sources needs some kind of a "Data retriever", which retrieves the data and updates it using the listener.update() method. But if all the "Data retrievers" share the very same listener, then it's not very performant, is it? Is it at all possible to create multiple adapters using the very same DataProvider class? I actually tried it and it didn't work, both adapters were retrieving data from the very same source, therefore my question.
I'd be grafteful for any hints.
Thanks
