Project Rationale |

Tycoon-2 is a direct successor of the languages
TooL and
Tycoon-1 developed by
our group since 1989. Some of its language concepts and can be explained best by a direct comparison with Java:
- Tycoon-2 is purely object-oriented (integers, arrays, classes, ... are treated as first-class objects)
- Tycoon-2 provides multiple inheritance (supporting a mixin-based programming style)
- Tycoon-2 has parametric polymorphism (type-parameterized classes and methods)
- Tycoon-2 has rich subtyping rules (covariant Self typing, higher-order subtyping)
- Tycoon-2 is higher-order (statically-scoped functions are first-class objects)
- Tycoon-2 provides orthogonal persistence (for data, code and threads)
- Tycoon-2 provides orthogonal mobility across platforms (for data, code and threads)
Similar to Java, Tycoon-2 provides strict typing, multithreading, full platform independence, exception
handling and garbage collection. Tycoon-2 is not designed to be (syntactically or implementation-wise) upward
compatible with Java.
Tycoon-2 is a reflective and bootstrapped system, i.e. its
language processors and development tools are accessible (in
a controlled and type-safe manner) to Tycoon-2 applications
and these core components are implemented in Tycoon-2
itself.
The Tycoon-2 system was developed and maintained by
Higher-Order.
Within the framework of a long-term research and
technology-transfer cooperation between
STS and Higher-Order, STS improves and utilizes
the Tycoon-2 system for its research and teaching work.
In particular, Tycoon-2 is the system platform for the following STS research projects:
Business Conversations,
MARINFO, and
Warburg Electronic Library.
Currently, Tycoon-2 is available on Unix platforms (Solaris 5.x,
HP-UX 10.x, Linux) and Windows NT 4.0. A freely available
distribution for academic purposes
is published under the GNU general public license (GPL)
and is available for download.
