Class NodeNavigator<A extends Activity>

ActivityBindingNavigator

io.scanbot.sdk.ui.utils.navigator.NodeNavigator<A>

All Implemented Interfaces:

Navigator

public class NodeNavigator<A extends Activity>
extends ActivityBindingNavigator

Navigator which navigates between interface NodeNavigator.NavigationNode.

You must call .bind before using the navigator and .unbind when bound Activity is about to be paused.

When navigator is being bound to again, it replays the last navigation node.

When navigator is about to be unbound - it calls NavigationNode.navigateFrom so you will have the chance to dispose resources associated with the node.
