This section shows you how to configure a network component by coding. Architecture of the Network Component later in this section goes into the details of the classes involved in the architecture of the network component.
The following example shows how to configure the network view through the API. See Network Component Services for programming details on the individual services.
IlpNetworkView view = network.getView();
//Toolbar
view.getToolBar().add(new IlpNetworkSelectButton(view));
view.getToolBar().add(new IlpNetworkZoomResetButton(view));
// Overview
view.setOverviewVisible(true);
// View interactor
IltSelectInteractor selInteractor = new IltSelectInteractor();
selInteractor.setEditingAllowed(true);
IlpViewsViewInteractor viewsInteractor =
new IlpViewsViewInteractor(selInteractor);
view.getController().setViewInteractor(viewsInteractor);
// Zoom policy
view.setZoomPolicy(
new IltMixedZoomPolicy() {{
setZoomThreshold(2.0);
}});
// Layout
view.setNodeLayout(new IlvGridLayout());
view.setLinkLayout(new IltShortLinkLayout());
// Background
view.addBackgroundURL(
context.getURLAccessService().getFileLocation(
"data/images/europe.jpg"));
// LayerPolicy
view.getCompositeGrapher().setLayerPolicy(myLayerPolicy)
// Position
view.setPositionConverter(
new IlpGeographicPositionConverter(projection,true));
The following example shows how to configure the network adapter through the API. See Network Component Services for programming details on the individual services.
IlpNetworkAdapter adapter = network.getAdapter(); // Filter IlpFilter myFilter = new MyFilter(); // (it is the same as network.setFilter(myFilter);) adapter.setFilter(myFilter); // Origin List myOrigins = new ArrayList(); myOrigins.add(objectID_1); myOrigins.add(objectID_2); : : myOrigins.add(objectID_n); // in this case we want to display the origins boolean showOrigin = true; adapter.setOrigins(myOrigins, showOrigin); // Expansion Strategy Factory // Usually the expansion strategy factory relies // on the adapter to access the data source and // to load/release objects IlpExpansionStrategyFactory myExpFactory = new MyExpansionStrategyFactory(adapter); adapter.setExpansionStrategyFactory(myExpFactory); // Position Attribute // Here, imagine that MyObject implements IlpObject // interface and defines "Placement" as the // IlpAttribute that defines the object position IlpClass myObjectClass = MyObject.getIlpClass(); IlpAttribute myPosAttrib = MyObject.Placement; adapter.setPositionAttribute(myObjectClass, myPosAttrib); // Node and Link Factory IlpNetworkNodeFactory myNodeFactory = new MyNodeFactory(); adapter.setNodeFactory(myNodeFactory); IlpNetworkLinkFactory myLinkFactory = new MyLinkFactory(); adapter.setLinkFactory(myLinkFactory);
