public java.lang.Object lookup(java.lang.String role) throws org.apache.avalon.framework.service.ServiceException
Object
associated with the given role. For
instance, If the ServiceManager
had a
LoggerComponent
stored and referenced by role, I would use
the following call:
try { MyComponent log; myComponent = (MyComponent) manager.lookup(MyComponent.ROLE); } catch (...) { ... }

role
- a string identifying the role to check.
public void release(java.lang.Object service)
Object
when you are finished with it. This
allows the ServiceManager
to handle the End-Of-Life Lifecycle
events associated with the Object
. Please note, that no
Exception should be thrown at this point. This is to allow easy use of the
ServiceManager system without having to trap Exceptions on a release.

object
- The Object
we are releasing.
