Sometimes a service may allow changes to its state to be made by external (remote) objects. This happens all the time to service locators, which have services added and removed. A service may wish to behave in the same manner as the locators, and just grant a lease for the change. After the lease has expired, the service will remove the change. Such a situation may occur with file classification, where a new service that can handle a particular MIME type starts: it can register the file name mapping with a file classifier service. However, the file classifier service will just time out the mapping unless the new service keeps it renewed. The example of this section follows the Granting and Handling Leases section in 8. It gives a concrete illustration of that section, now that there is enough background to do so.

The implementation changes in several ways from the forms we saw earlier. Since it now needs to handle a changing set of MIME types, the types are stored in a map, and lookups are done on this map. Adding and removing types is also done through this map. In addition, adding types now needs to return a lease so that the additions will only last as long as the lease is valid; for this, the implementation will use a landlord to grant and manage leases.

The landlord implements the Landlord interface. In addition, it has a newFileClassifierLease() method, which is called by addType(). The implementation looks like this: package lease; import java.rmi.Remote; import java.rmi.RemoteException; import net.jini.core.lease.Lease; import net.jini.core.lease.LeaseDeniedException; import com.sun.jini.landlord.Landlord; import common.MIMEType; import common.LeaseFileClassifier; import java.util.Map; import java.util.HashMap; /** * FileClassifierImpl.java */ public class FileClassifierImpl implements RemoteLeaseFileClassifier { public final long DURATION = 2*60*1000L; // 2 minutes /** * Map of String extensions to MIME types */ protected Map map = new HashMap(); protected transient FileClassifierLandlord landlord; public MIMEType getMIMEType(String fileName) { System.out.println("Called with " + fileName); MIMEType type; String fileExtension; int dotIndex = fileName.lastIndexOf('.'); if (dotIndex == -1 || dotIndex + 1 == fileName.length()) { // can't find suitable suffix return null; } fileExtension= fileName.substring(dotIndex + 1); type = (MIMEType) map.get(fileExtension); return type; } public Lease addType(String suffix, MIMEType type) throws LeaseDeniedException { if (map.containsKey(suffix)) { throw new LeaseDeniedException("Extension already has a MIME type"); } map.put(suffix, type); System.out.println("type added"); Lease lease = landlord.newFileClassifierLease(this, suffix, DURATION); System.out.println("Lease is " + lease); return lease;
