Class CoreSubsystem

java.lang.Object
  org.alliance.core.CoreSubsystem

All Implemented Interfaces:

Subsystem

public class CoreSubsystem
extends java.lang.Object
implements Subsystem

This is the core of the entire Alliance system. Theres not too much code here, it's more of a hub for the entire Core subsystem. Has a instance of FriendManager, FileManager, NetworkManager, InvitatationManager and the UICallback.

This class contains the oh-so-important invokeLater method that HAS to be used when code in the Core subsystem need to be run from another thread than the Core thread. Very much like SwingUtilities.invokeLater().

There's also a que of NeedsUserInteractions. This is an interface that is used when something happens in the Core subsystem that the user need to interact to. Examples are: chat message received, invitation code received etc.. These things are queued by the Core subsystem and fethed by the UI subsystem Created by IntelliJ IDEA.

getUICallback

public UICallback getUICallback()

setUiCallback

public void setUiCallback(UICallback uiCallback)

getFileManager

public FileManager getFileManager()

invokeLater

public void invokeLater(java.lang.Runnable runnable)

The core package is not thread safe. It all runs in one thread. If another threads want to invoke something in core it should use this method. Same design pattern as SwingUtilities.invokeLater

runnable -

reportError

public void reportError(java.lang.Throwable e,
                        java.lang.Object source)

Throws:

java.io.IOException

uiToFront

public void uiToFront()

getInvitaitonManager

public InvitaitonManager getInvitaitonManager()

queNeedsUserInteraction

public void queNeedsUserInteraction(NeedsUserInteraction ui)

fetchUserInteraction

public NeedsUserInteraction fetchUserInteraction()
