[Evolution-hackers] Addressbook backendquestions

[Steven Zhang <steven zhang sun com>]

I am reading the backend code of evolution and found that the request to 
backend include the following type:
CreateCard / RemoveCards / ModifyCard / CheckConnection / GetVCard / 
GetCursor / GetBookView /
GetCompletionView / GetChanges / AuthenticateUser / GetSupportedFields 
/  GetSupportedAuthMethods
I can understand most of the request. But to some request operations, I 
don't know what is its purpose, such as :
GetCursor, GetChanges, GetSupportedFields. I can not get any idea from 
the code, and no comments in the code.
So Chris, do you like to give me some info about the backend of 
Addressbook. What GetCursor/GetChanges do, what is the different between 
Modify and GetChanges. And I don't know where CompletionView is defined, 
and it's purpose.

From my understanding, I think that UI will create the request and 
backend will handle the request, send result back to UI.

Regards.
