------------------------------------------
Hi,
I've finally 'revert' my solution. The previous mentioned solution introduced a
lot of annotations and the resulting user-code was quite messy (so support all
the type of possible configurations).
So, I've decided a fairly more simple solution. I propose to use one annotation
: @Instantiate. On a @Component annotated class it will create one instance
automatically. The instance is created without configuration.
@Instantiate
@Component
public class MyComponent {
...
}
For more complexes use cases (application/configuration description), I
encourage to use this annotation on a component implementation using the iPOJO
API to create the instances and compositions. So, it is possible to use the
complete range of iPOJO features that way:
@Instantiate
@Component
public class MyApplicationConfiguration {
@Requires(filter="(factory.name=my.factory)")
private Factory myFactory;
@Requires(filter="(factory.name=my.factory.2)")
private Factory mySecondFactory;
ComponentInstance instance1, instance2;
@Validate
public void configure() {
instance1 = myFactory.createComponentInstance(null);
instance2 = mySecondFactory.createComponentInstance(null);
}
@Invalidate
public void shutdown() {
instance1.dispose();
instance2.dispose();
}
}
> Add @Instance annotation to declare instances without metadata.xml
