Yes. Pooled components are not used by more than one client at a time,
and it should be possible to grab two of them.
For example:
interface MyPooledComponent {
/**
* Call this one just as you obtain the component.
*/
public void A ();
/**
* Must be called after A.
*/
public void B ();
/**
* Must be called after B.
*/
public void C ();
}
(In Cocoon, MyPooledComponent -> Transformer, MyPooledComponent.A ->
Transformer.setup,
so this is a real-life use case. One should be able to grab two transformers
to
create a pipeline.)
