Abstract
When writing a program to be executed in the worldwide object-oriented distributed systems environment, the source code may include class names developed at other sites. In this case, using the class name as a runtime class identifier, which should be globally unique, may cause problems such as: 1) The same class name representing a different class is found in another site. 2) Classes using different versions of a class cannot work together. To tackle these problems, the authors proposed and implemented a local class name facility called ‘chool. The school facility separates the compile time class name and the runtime class identity. This paper describes our design and implementation of the school and the runtime class identity in the OZ++ system: a worldwide object-oriented distributed systems environment developed by the authors.
