Class ConnectionStateMachine

java.lang.Object

eu.hgross.blaubot.core.statemachine.ConnectionStateMachine

public class ConnectionStateMachine
extends java.lang.Object

Statemachine for the network creation. Simply delegates the events from the BlaubotConnectionManager and the AbstractBlaubotDeviceDiscoveryEvents from the beacons to the current state. The state will handle the event based state changes by themselves (calling nextState).
