clazz
- the class of the bean- Returns:
- the first bean of a specific class (or subclass), or null if no such bean exist
-
removeBean
boolean removeBean(java.lang.Object o)
Removes the given bean. If the bean is-aContainer.Listener
, then also do an implicitremoveEventListener(Listener)

isManaged
boolean isManaged(java.lang.Object bean)
Test if this container manages a bean- Parameters:
bean
