Imported Service Properties

Subclasses of BaseBundleActivator can query the properties of an imported service using the methods getImportedServicePropertyKeys(String) and getImportedServiceProperty(String, Object). For example:

   protected void activate() {
     String[] keys = getImportedServicePropertyKeys(CounterService.SERVICE_NAME);
     String key;
     Object value;
     System.out.println("CounterService Properties:");
     for (int i = 0; i < keys.length; i++) {
       key = keys [ i ];
       value = getImportedServiceProperty(CounterService.SERVICE_NAME, key);
       System.out.println(key + " = " + value);
     }
   }

The query method getImportedServicePropertyKeys(String) is used to retrieve a String[] of property keys for an imported service. Of course this is not necessary if the property keys are already known.
The query method getImportedServiceProperty(String, String) is used to retrieve the value of an imported service property matching the specified key.
It is not possible to set the value of an imported service property; only the bundle that exported the service can do this.
