Class ExchangeStatesTask

java.lang.Object

eu.hgross.blaubot.core.acceptor.discovery.ExchangeStatesTask

All Implemented Interfaces:

java.lang.Runnable

public class ExchangeStatesTask
extends java.lang.Object
implements java.lang.Runnable

A task that utilizes a given (and connected) IBlaubotConnection to exchange the given State with the remote endpoint. The remote endpoint is the BlaubotBeaconService's BeaconConnectionHandler-Runnable. This task does the whole beacon exchange heavy lifting and can be reused in other beacon implementations. If the exchange is successful, the IBlaubotDiscoveryEventListener is informed about the discovered state of the remote endpoint. After the execution the connection is closed.

ExchangeStatesTask

public ExchangeStatesTask(IBlaubotDevice ownDevice,
                          IBlaubotConnection connection,
                          IBlaubotState ourState,

                          IBlaubotDiscoveryEventListener eventListener)

Creates a new ExchangeStatesTask to be used with a IBlaubotBeaconInterface implementation.

Parameters:

ownDevice - our own device

connection - the connection newly created connection to the remote beacon

ourState - our own state that is going to be exchanged with the other side's (accepting) beacon

ourAcceptorMetaData - the list of connection meta data objects gathered from OUR OWN acceptors

beaconStore - the beacon store to get connection meta data for other devices from

eventListener - the event listener of our beacon, which will be called with the appropriate discovery event by this task
