0N/A/**
0N/A * <p>
0N/A * This interface is implemented by a JavaBean that does
0N/A * not directly have a BeanContext(Child) associated with
0N/A * it (via implementing that interface or a subinterface thereof),
0N/A * but has a public BeanContext(Child) delegated from it.
0N/A * For example, a subclass of java.awt.Container may have a BeanContext
0N/A * associated with it that all Component children of that Container shall
0N/A * be contained within.
0N/A * </p>
0N/A * <p>
0N/A * An Object may not implement this interface and the
0N/A * BeanContextChild interface
0N/A * (or any subinterfaces thereof) they are mutually exclusive.
0N/A * </p>
0N/A * <p>
0N/A * Callers of this interface shall examine the return type in order to
0N/A * obtain a particular subinterface of BeanContextChild as follows:
0N/A * <code>
0N/A * BeanContextChild bcc = o.getBeanContextProxy();
0N/A *
0N/A * if (bcc instanceof BeanContext) {
0N/A * // ...
0N/A * }
0N/A * </code>
0N/A * or
0N/A * <code>
0N/A * BeanContextChild bcc = o.getBeanContextProxy();
0N/A * BeanContext bc = null;
0N/A *
0N/A * try {
0N/A * bc = (BeanContext)bcc;
0N/A * } catch (ClassCastException cce) {
0N/A * // cast failed, bcc is not an instanceof BeanContext
0N/A * }
0N/A * </code>
0N/A * </p>
0N/A * <p>
0N/A * The return value is a constant for the lifetime of the implementing
0N/A * instance
0N/A * </p>
