* TODO
|
|
Pass cause back to client somehow via FailureResponse in Client.requestFailed
|
|
|
|
clientWillLogff becomes clientMayLogoff?
|
|
|
|
Look into nbio waking up all sockets when any data comes in.
|
|
|
|
(maybe) Allow piggybacking of object subscription onto service defined
|
|
responses (like moveTo request).
|
|
|
|
(maybe) Allow better server side control of subscription management (to
|
|
ensure that clients don't remain subscribed to objects they should no
|
|
longer be susbcribed to; like scenes they've departed from).
|
|
|
|
Sort out support for server-side modifiable only fields to DObject.
|
|
|
|
Create a CompoundEvent that allows packaging up of multiple events to be
|
|
dispatched in unison. Build dobj source generator and have it add versions
|
|
of all update methods that take a compound event to which to append the
|
|
event rather than dispatching them directly.
|
|
|
|
Maybe make AuthResponseData a Streamable instead of a DObject.
|
|
|
|
Have the LocationRegistry register the LocationProvider rather than doing
|
|
it via a config file. Perhaps lose the config file element altogether.
|
|
|
|
Think about Subscriber business and whether or not DObject needs a list of
|
|
subscribers or if there's a better way to handle removedLastSubscriber()
|
|
on the client side and not taint the server side with all dat crap.
|
|
|
|
* Server-side event concentrator
|
|
The client objects will not subscribe directly, but will subscribe through
|
|
the concentrator so that, at least, it can create a single
|
|
ForwardEventNotification for each Event being dispatched to a group of
|
|
clients. Optimally, it would be able to flatten that notification as well
|
|
and the byte array can be written to the socket of each of the individual
|
|
clients rather than creating a separate byte array for each client. This
|
|
will require a special "flattened notification" that can be inserted into
|
|
the queue to preserve message ordering but then is simply sent rather than
|
|
flattened and sent.
|
|
|
|
* 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.
|
|
|
|
* Client network mgmt
|
|
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 ();
|
|
}
|
|
|
|
* DObject class generation
|
|
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 ();
|
|
}
|
