MarsProxyPlugin

public class ProxyPlugin
extends EnginePlugin
implements MessageCallback, multiverse.server.network.ClientConnection.AcceptCallback, multiverse.server.network.ClientConnection.MessageCallback

The ProxyPlugin is the sole plugin charged to communicate with clients. The onActivate method opens both TCP and RDP listeners, both on the same port, allowing clients to connect over TCP are RDP.

Messages from other plugins are delvered to the PluginMessageCallback's handleMessage() method by the MessageAgent, and are queued in a SquareQueue instance based on the player oid for which they are intended.

Similarly, events stream in from clients via calls to the processPacket() method, where the events are parsed and and queued in another SquareQueue reserved for events. Ultimately the SquareQueue calls a callback to process the event.

Initilizes display of message processing time histograms.

Enumerates the list of properties in PropertyMessages that don't need to be sent to the client, because the client doesn't pay attention to them. This is not yet customizable, but should be.

Calls registerHooks to enumerate the proxy's message processing hooks.

Establishes the PerceptionFilter for the many message types sent by other plugins, to which players and other objects will be added as the are created, and creates the master subscription using the PerceptionFilter. This is not yet customizable, but should be.

Creates and opens the RDP listener using the proxy listener port.

Creates and opens the TCP listener using the proxy listern port.
