Get drive item changes

The following example shows you how to get drive item changes (delta query). The delta query lets you track changes to drive items without having to fetch the entire drive every time.

import com.independentsoft.graph.GraphClient;
import com.independentsoft.graph.GraphException;
import com.independentsoft.graph.files.DriveItem;
import com.independentsoft.graph.files.DriveItemChanges;

public class Console {

	public static void main(String[] args)
	{
		try
		{
			GraphClient client = new GraphClient();

			client.setClientId("63333333-209e-454e-b7bd-55a4d201270f");
			client.setTenant("independentsoft.onmicrosoft.com");
			client.setUsername("info@independentsoft.onmicrosoft.com");
			client.setPassword("password");

			DriveItemChanges driveItemChanges = client.getDriveItemChanges();

			for (DriveItem item : driveItemChanges.getDriveItems())
			{
				System.out.println("Name: " + item.getName());
			}

			String deltaLink = driveItemChanges.getDeltaLink();

			System.out.println("Delta link: " + deltaLink);

			// Later, use the deltaLink to get only the changes since the last call
			// DriveItemChanges newChanges = client.getDriveItemChanges(deltaLink);
		}
		catch (GraphException e)
		{
			System.out.println(e.getCode());
			System.out.println(e.getMessage());

			e.printStackTrace();
		}
		catch (Exception e)
		{
			e.printStackTrace();
		}
	}
}
