  /**
   * Implements all four flavors of binding. It uses Resolve() to check if a binding already exists
   * (for bind and bind_context), and unbind() to ensure that a binding does not already exist. If
   * the length of the name is 1, then Bind() is called with the name and the object to bind.
   * Otherwise, the first component of the name is resolved in this NamingContext and the
   * appropriate form of bind passed to the resulting NamingContext. This method is static for
   * maximal reuse - even for extended naming context implementations where the recursive semantics
   * still apply.
   *
   * @param impl an implementation of NamingContextDataStore
   * @param n a sequence of NameComponents which is the name under which the object will be bound.
   * @param obj the object reference to be bound.
   * @param rebind Replace an existing binding or not.
   * @param bt Type of binding (as object or as context).
   * @exception org.omg.CosNaming.NamingContextPackage.NotFound A name with multiple components was
   *     supplied, but the first component could not be resolved.
   * @exception org.omg.CosNaming.NamingContextPackage.CannotProceed Could not * proceed in
   *     resolving the first component of the supplied name.
   * @exception org.omg.CosNaming.NamingContextPackage.InvalidName The supplied name is invalid
   *     (i.e., has length less than 1).
   * @exception org.omg.CosNaming.NamingContextPackage.AlreadyBound An object is already bound under
