public class MetaBlocker
  extends MetaObject

A MetaBlocker is installed as the primary MetaObject of an Object from the moment in which it is created with `new' up to the moment in which the MetaObject of its creator returns from the invocation of the method configure. It rejects all Operations, throwing Blocked (an inner class) exceptions. If such a MetaObject is installed on an Object in any other case, the Object becomes totally unusable.
