  Constructor.
  The constructed channel gives read/write access to the variable value. The variable value must not be destroyed as long as this channel is active.

  virtual DirectChannel* clone ()const ;

  virtual bool get (double&)const ;

  Fetch from channel.
  If the channel can be read, set value and return true, otherwise return false.

  virtual bool set (double) ;

  Store into channel.
  If the channel can be written, store value into it and return true, otherwise return false.
