Interface Controller

All Superinterfaces:

AutoCloseable, Closeable

All Known Implementing Classes:

ControllerImpl

public interface Controller
extends Closeable

Service that allows one Drillbit to communicate with another. Internally manages whether each particular bit is a server or a client depending on who initially made the connection. If no connection exists, the Controller is responsible for making a connection. TODO: Controller should automatically straight route local BitCommunication rather than connecting to its self.
