Displaying a default data value graph

You can write a sample service that opens a default data value and relationship graph based on a user's record selection. Note that default data value graphs require no prior configuration in the UI. The API also allows you to determine display of certain graph features. As shown in the following sample, the Overview map has been removed. Additionally, record details are disabled which prevents the end-user from double-clicking a node to open the record.

public class DefaultDataValueGraph implements UserService<RecordEntitySelection>
{

	@Override
	public void setupObjectContext(
		UserServiceSetupObjectContext<RecordEntitySelection> context,
		UserServiceObjectContextBuilder builder)
	{
	}

	@Override
	public void setupDisplay(
		UserServiceSetupDisplayContext<RecordEntitySelection> context,
		UserServiceDisplayConfigurator config)

	{

		final Adaptation record = context.getEntitySelection().getRecord();

		if (record != null)
		{
			UIButtonSpecNavigation close = config.newCloseButton();
			close.setDefaultButton(true);

			config.setContent(new UserServicePane()
			{
				@Override
				public void writePane(UserServicePaneContext context, UserServicePaneWriter writer)
				{

					//Disable display of the Overview box
					GraphDataSpec spec = new GraphDataSpec();
					spec.setOverviewDisplay(OverviewDisplayOptions.DISABLE);
					
					//Prevent users from accessing a detailed view of records
					spec.disableFeatures(GraphDataFeatures.RECORD_DETAILS);

					UIHttpManagerComponent comp = GraphDataHttpManagerComponentUtils
						.getComponentForGraphDataService(writer, record, spec);

					writer.add("<div id='incrementalDataContainerTab' style='height: 100%;'>");
					writer.add("<iframe id='incrementalDataTabIframe' width='100%' height='100%'");

					String url = comp.getURIWithParameters();
					writer.add(
						" frameBorder='0' style='border-width: 0px; ' src='" + url + "'></iframe>");
					writer.add("</div>");
					writer.addJS_cr(
						"var incrementalDataContainerTabElement = document.getElementById('incrementalDataContainerTab');");

					writer.addJS_cr("function resizeIncrementalDataTab(size){");
					{
						writer.addJS_cr(
							"incrementalDataContainerTabElement.style.width = size.w + 'px';");
						writer.addJS_cr(
							"incrementalDataContainerTabElement.style.height = size.h + 'px';");
					}
					writer.addJS_cr("}");
					writer.addJS_addResizeWorkspaceListener("resizeIncrementalDataTab");
				}
			});
		}
	}

	@Override
	public void validate(UserServiceValidateContext<RecordEntitySelection> context)
	{
	}

	@Override
	public UserServiceEventOutcome processEventOutcome(
		UserServiceProcessEventOutcomeContext<RecordEntitySelection> context,
		UserServiceEventOutcome eventOutcome)
	{
		return null;
	}
