= Analysis =


== Overview ==

This task is about redesigning the current connectivity model according to the new resource model and improving it so it reaches a stable beta phase.

Since there are too many tasks about server and connectivity,they first need to be categorized, analyzed and scheduled. A clear vision for further procedure is needed - this task is about doing so.


== Task requirements ==

Analyze the current status and what needs to be done for the following:
 * The whole connectivity design must be revised (in this task) - what does is consist of, how does the client use the connectivity module, etc.
 * Facade - since the resources are being redesigned, the facade needs to be changed. Real time collaboration support should be provided (sync methods).
 * Connection list - the connection list in the client needs to be persisted, should provide manipulation ability, connections need to have clear statuses defined. 
 * Server resource listing - the client needs to have a clear way of getting server resource lists (keeping in mind the security permissions). Also, needs to have filtering, searching, open/close support. This issue affects the server, too. 
 * Client U.I. - there is currently a tab for the server stuff in the left flap, it must be re-designed and synchronized with our analysis men.
 * Security - there is already some user/group model, but no logic is using it. Analyze / design the base security model.

== Task result ==
 * In the design - design documentation for every connectivity aspect discussed above. Design diagrams are needed, auto tests are obligatory.
 * In the implementation - Achievable schedule of what will be accomplished in what time, considering connectivity. The common design must be implemented as a basis for the next tasks. The tasks which will be implemented should be grouped and (optionally) analyzed. 

== Implementation idea ==
 * The base.connectivity module currently does not maintain the list of the available connections - they are kept in the corresponding palette. Consider this behavior. 
 * There is a design draft for the new resource facade after the resource redesign - [http://pastebin.asteasolutions.net/f444cc8f1]. Another idea is that the client implementation of the facade is used by the server resource accesses, and the server-side implementation uses the server resource accesses.
 * Connection listing should mainly use the server resource access, so it must be synchronized with other teams' work.

== How to demo ==
Explain the complete model to the teams. Show the working prototypical code.

= Design =
 * ServerConnection:
  * Represents a connection to a server, instantiated from a given Account. 
  * Every connection has 1:1 relation with a client-side facade.
  * Has the methods that the facade has, which delegate to the facade's ones.
  * The main difference between a connection and a facade is that the facade needs Session ID for its methods. 
  * The facade's methods always return objects of type Response, the connection's ones handle the responses and 'unwrap' them.
  * The facade is not visible to others, only to the connection.
  * The methods in the !ServerConnection that the facade doesn't have are login(String username, String password), logout(), connect() and disconnect(). The third one is responsible for getting a session ID from the server and instantiating the private facade, the last one is responsible for destroying the facade in the connection and setting sessionId to null.
