+/**
+ * A low-level event which indicates that a container's contents
+ * changed because a component was added or removed.
+ * <P>
+ * Container events are provided for notification purposes ONLY;
+ * The AWT will automatically handle changes to the containers
+ * contents internally so that the program works properly regardless of
+ * whether the program is receiving these events or not.
+ * <P>
+ * This low-level event is generated by a container object (such as a
+ * Panel) when a component is added to it or removed from it.
+ * The event is passed to every <code>ContainerListener</code>
+ * or <code>ContainerAdapter</code> object which registered to receive such
+ * events using the component's <code>addContainerListener</code> method.
+ * (<code>ContainerAdapter</code> objects implement the
+ * <code>ContainerListener</code> interface.) Each such listener object
+ * gets this <code>ContainerEvent</code> when the event occurs.
+ * <p>
+ * An unspecified behavior will be caused if the {@code id} parameter
+ * of any particular {@code ContainerEvent} instance is not
+ * in the range from {@code CONTAINER_FIRST} to {@code CONTAINER_LAST}.
+ *
+ * @see ContainerAdapter
+ * @see ContainerListener
