[picocontainer-scm] [jira] Created: (PICO-369) generic signature of ComponentAdapter#getComponentImplementation

generic signature of ComponentAdapter#getComponentImplementation
----------------------------------------------------------------

                 Key: PICO-369
                 URL: http://jira.codehaus.org/browse/PICO-369
             Project: PicoContainer
          Issue Type: Improvement
          Components: PicoContainer (Java)
    Affects Versions: 2.9
            Reporter: Giorgio Gallo
            Priority: Minor


The signature of method ComponentAdapter#getComponentImplementation is currently

Class<T> getComponentImplementation();

To me it feels like

Class<? extends T> getComponentImplementation();

should be used instead, in order to allow (eg) for

public class MyAdapter implements ComponentAdapter<List> {

  private Class<? extends List> implementationclass = ArrayList.class;

  public Class<? extends List> getComponentImplementation() {
    return implementationclass;
  }

  // ...
}

(the above is adapted from a real case I got into while integrating pico with stripes - I want to implement an adapter which resolves to whatever ActionBeanContext class is configured in web.xml and so there is no way I can statically type the T of ComponentAdapter)
