-/**
- * Beans implement this to get information about the execution environment and its services and to be placed in the hierarchy.
- * <P>
- *
- * The difference between a <code>BeanContext</code> and a
- * <code>BeanContextChild</code>, mainly, is that a
- * <code>BeanContext</code> may be a parent.
- * <P>
- *
- * <code>BeanContextChild</code> instances will be serialized at some
- * point in their life, but you need to make sure your bean context does
- * not contain a serializable reference (directly or indirectly) to the
- * parent <code>BeanContext</code>, to any of the other
- * <code>BeanContext</code>s in the tree, or to any resources obtained
- * via the <code>BeanContextServices</code> interface. One way to do this
- * is to mark any fields that contain such references as
- * <code>transient</code>. Another way is to use a custom serializer.
- * <P>
- *
- * If you do not do this, when the <code>BeanContext</code> is serialized,
- * all the other <code>BeanContext</code>s and other unnecessary things
- * will be serialized along with it.
- * <P>
- *
- * Before dying, a <code>BeanContextChild</code> should call
- * <code>getBeanContext().remove(this)</code> to detach from the
- * hierarchy and exit cleanly.

- * When this Object is being added to a new BeanContext or moved
- * from an old one, a non-null value will be passed in.
- * <P>
- *
- * When this Object is being removed from the current
- * <code>BeanContext</code>, <code>setBeanContext()</code> will

- * If the Bean does not wish to change the parent or be removed
- * from one, it may throw the <code>PropertyVetoException</code>.

- * you from being removed from the <code>BeanContext</code> so
- * that you can <em>not</em> veto it the next time.
- * Otherwise, nasty pathological recursion stuff could occur in
- * certain situations.
- * <P>
- *
- * 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.
