TooL: Object Oriented Tycoon

Andreas Gawecki (1/94-3/96)

Goal

Type system support for a pure object-oriented library programming style which also provides a testbed for advanced static and dynamic optimizations in database environments.

Code Samples

Take a glance at the TooL class library: Hierarchy Overview. Class Index.

Classes containing interesting code are, for example, Int, Container, Dictionary, and ReadStream.
