+@deftypemethod BeanContextChildComponentProxy {public Component} getComponent ()

+@end deftypemethod
+@deftypemethod BeanContextChild {public void} setBeanContext (java.beans.beancontext.BeanContext@w{ }@var{parent}) @*throws PropertyVetoException
+Set the parent @code{BeanContext}.
+
+
+
+
+ This method is called from @code{BeanContext.add()} and
+ should not be called directly.
+
+
+
+
+ When this Object is being added to a new BeanContext or moved
+ from an old one, a non-null value will be passed in.
+
+
+
+
+ When this Object is being removed from the current
+ @code{BeanContext}, @code{setBeanContext()} will
+ receive the parameter @code{null}.
+
+
+
+
+ When being removed from the current @code{BeanContext},
+ it is the @code{BeanContextChild}'s responsibility to
+ release all services it has obtained.
+
+
+
+
+ This change should generate @code{PropertyChangeEvent}
+ and @code{VetoableChangeEvent}s with the property name
+ "beanContext". If the change is vetoed, it must re-throw the
+ exception and not change anything. In this way, the parent
+ @code{BeanContextChild}, who has registered himself with
+ you, will have a chance to remove this child from its
+ collection.
+
+
+
+
+ If the Bean does not wish to change the parent or be removed
+ from one, it may throw the @code{PropertyVetoException}.
+ If you veto a @code{setBeanContext(null)} call, then you
+ should try your hardest to remedy whatever problem is keeping
+ you from being removed from the @code{BeanContext} so
+ that you can <em>not</em> veto it the next time.
+ Otherwise, nasty pathological recursion stuff could occur in
+ certain situations.
+
+
+
+
+ If you do veto the change, you must first back out any changes
+ you made prior to the veto. Best not to make any such changes
+ prior to the veto in the first place.

+
+
+
+ This method is called from @code{BeanContext.add()} and

+ @code{validatePendingSetBeanContext()}. If this call
