Class DefaultLocationManager

java.lang.Object
  org.opennms.features.poller.remote.gwt.client.DefaultLocationManager

All Implemented Interfaces:

com.google.gwt.event.shared.EventHandler, ApplicationDeselectedEventHandler, ApplicationSelectedEventHandler, GWTMarkerClickedEventHandler, GWTMarkerInfoWindowRefreshHandler, LocationPanelSelectEventHandler, MapPanelBoundsChangedEventHandler, FilterPanel.FiltersChangedEventHandler, FilterPanel.StatusSelectionChangedEventHandler, LocationManager, MapRemoteEventHandler, RemotePollerPresenter, TagPanel.TagClearedEventHandler, TagPanel.TagSelectedEventHandler

public class DefaultLocationManager
extends Object
implements LocationManager, RemotePollerPresenter

This class implements both LocationManager (the model portion of the webapp) and RemotePollerPresenter (the controller portion of the webapp code). It is responsible for maintaining the knowledgebase of Location objects and responding to events triggered when:

• Location instances are added or m_updated
• the UI elements are clicked on by the user

If this class ever grows too large, we can split it into separate model and controller classes.

Since:

1.8.1
