Interface ManagedServiceFactory</H2>
<HR>
<DL>
<DT><PRE>public interface <B>ManagedServiceFactory</B></DL>
</PRE>
<P>
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,
"com.acme.serialportfactory" );
registration = context.registerService(
ManagedServiceFactory.class.getName(),
this,
properties
);
}
public void updated( String pid,
Dictionary properties ) {
String portName = (String) properties.get("port");
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 );
}
...
}

<DL>
<DD>Create a new instance, or update the configuration of an existing
instance.
If the PID of the <code>Configuration</code> object is new for the
Managed Service Factory, then create a new factory instance, using the
configuration <code>properties</code> provided. Else, update the
service instance with the provided <code>properties</code>.
<p>
If the factory instance is registered with the Framework, then the
configuration <code>properties</code> should be copied to its registry
properties. This is not mandatory and security sensitive properties
should obviously not be copied.
<p>
If this method throws any <code>Exception</code>, the Configuration
Admin service must catch it and should log it.
<p>
When the implementation of updated detects any kind of error in the
configuration properties, it should create a new
<A HREF="../../../../org/osgi/service/cm/ConfigurationException.html" title="class in org.osgi.service.cm"><CODE>ConfigurationException</CODE></A> which describes the problem.
<p>
The Configuration Admin service must call this method asynchronously.
This implies that implementors of the <code>ManagedServiceFactory</code>
class can be assured that the callback will not take place during
registration when they execute the registration in a synchronized method.
