org.cougaar.core.node
Class AddServiceComponent

java.lang.Object
  org.cougaar.util.GenericStateModelAdapter
      org.cougaar.core.node.AddServiceComponent

All Implemented Interfaces:

org.cougaar.core.component.Component, org.cougaar.util.GenericStateModel

public class AddServiceComponent
extends org.cougaar.util.GenericStateModelAdapter
implements org.cougaar.core.component.Component

This component can be used to import an external service into the node agent.

For example, the NodeApplet uses this component to advertise the AppletService.

Two parameters are required:
1) The Service class or classname.
2) The Service class, classname, or instance, or the ServiceProvider class, classname, or instance.
A third parameter is optional:
3) "true" to use the root ServiceBroker, defaults to false.

Reflection is used wrap the 2nd parameter as the correct API, even if it doesn't implement the correct interface. For example, an external client can specify an implementation for:

   public interface FooService extends Service {
     void foo();
   }
 

as:

   public class MyFoo {
     public void foo() { .. }
   }
 

even though "MyFoo instanceof FooService" is false. This is supported to avoid awkward compile and classloader dependencies.
