 <pre>public interface <span class="strong">ManagedServiceFactory</span></pre>
 <div class="block">Manage multiple service instances.

  Bundles registering this interface are giving the Configuration Admin service
  the ability to create and configure a number of instances of a service that
  the implementing bundle can provide. For example, a bundle implementing a
  DHCP server could be instantiated multiple times for different interfaces
  using a factory.

  <p>
  Each of these <i>service instances </i> is represented, in the persistent
  storage of the Configuration Admin service, by a factory
  <code>Configuration</code> object that has a PID. When such a
  <code>Configuration</code> is updated, the Configuration Admin service
  calls the <code>ManagedServiceFactory</code> updated method with the new
  properties. When <code>updated</code> is called with a new PID, the Managed
  Service Factory should create a new factory instance based on these
  configuration properties. When called with a PID that it has seen before, it
  should update that existing service instance with the new configuration
  information.

  <p>
  In general it is expected that the implementation of this interface will
  maintain a data structure that maps PIDs to the factory instances that it has
  created. The semantics of a factory instance are defined by the Managed
  Service Factory. However, if the factory instance is registered as a service
  object with the service registry, its PID should match the PID of the
  corresponding <code>Configuration</code> object (but it should <b>not </b>
  be registered as a Managed Service!).

  <p>
  An example that demonstrates the use of a factory. It will create serial
  ports under command of the Configuration Admin service.

  <pre>

    class SerialPortFactory
      implements ManagedServiceFactory {
      ServiceRegistration registration;
      Hashtable ports;
      void start(BundleContext context) {
        Hashtable properties = new Hashtable();
        properties.put( Constants.SERVICE_PID,
          &quot;com.acme.serialportfactory&quot; );
        registration = context.registerService(
          ManagedServiceFactory.class.getName(),
          this,
          properties
        );
      }
      public void updated( String pid,
        Dictionary properties  ) {
        String portName = (String) properties.get(&quot;port&quot;);
        SerialPortService port =
          (SerialPort) ports.get( pid );
        if ( port == null ) {
          port = new SerialPortService();
          ports.put( pid, port );
          port.open();
        }
        if ( port.getPortName().equals(portName) )
          return;
        port.setPortName( portName );
      }
      public void deleted( String pid ) {
        SerialPortService port =
          (SerialPort) ports.get( pid );
        port.close();
        ports.remove( pid );
      }
