Hi, all.
     If I want to get some data from other module of app, what should I do?


     I know we can use CONTEXT to get the app as a service, and then we can get 
the data in that app. But, the logic of these two app is not about producer and 
consumer.
     The second method to get this data is using API. So, I have to build some 
API just like topology' API. However , I notice that Switches in topology just 
return the new data, if I want to write something into that data, it won't 
change the real data.
     Obviously, use import just can get the static defined data of using 
methods, we can't get the data of an alive object.


     So, what I need is a method to share the data between tow apps. 
     
     Thank you for your time.
