Cher Mk3 Notes -*- outline -*-
* Marshaller
Consider how the dobject marshaller deals with classes loaded and reloaded
using flushable classloaders.
Also consider whether access to the marshaller cache needs to be
synchronized.
* Check into "connection closed by peer" thread exiting on client
* TypedObjectFactory
Maybe modify so that types are assigned automatically even if everything
has to be registered in a single place, since it pretty much does anyway.
* Server components:
+ Connection manager
+ Client manager
+ Event dispatch thread (DObjectManager)
+ Server side services?
+ Room/Game managers
+ Info repository for shared info?
* Client components:
+ Network client (auth + DObject services)
+ Applet shell
+ Panel management
+ Components: chatbox, occupant info, turn indicator?
+ Room/Game panels, controllers, etc.
* Client detail:
+ Supply credentials (username, password)
+ Establishes, maintains connection:
login (connect), logout (disconnect)
+ Creates, manages client-side DObjectManager
* Events in the client will be dispatched on the AWT thread
- Provide pluggable "event dispatcher" on the client
- Allow extension of Event as DispatchableEvent so that event objects
themselves can extend Runnable and be popped right into
SwingUtil.invokeLater().
* Client perform all network ops on own thread, will call back to main
code through Observer interface to notify of state changes in the
authentication process/connectedness:
public interface ClientObserver
{
public void didConnect ();
public void connectionFailed ();
public void didLogon ();
public void logonFailed ();
public void didDisconnect ();
public void didLogoff ();
}
* Three Rings Client flowlist:
Instantiate client
Obtain auth info
Obtain room info
Authenticate
* Distributed objects are defined like a class with a set of public data
members which is then converted into an actual class with get/set
methods for each member.
public dclass GameObject
{
public int[] players;
public String description;
}
becomes
public class GameObject extends DObject
{
public void setPlayers (int[] players);
public void setPlayersAt (int index, int value);
public int[] getPlayers ();
public int getPlayersAt (int index);
public void setDescription (String description);
public String getDescription ();
}
