  Deprecated
  Set the value of not

  Specified by:
    `setNot` in interface `Expression`

### value

    public Object value()

  Deprecated
  value() is a more typesafe implementation of clone()

### setByValue

    public void setByValue(Object value)

  Deprecated
  It is possible to call set-by-value with a superclass.
