Overview

Zonnon is a member of the Pascal family of languages, which has two beneficial consequences: a) it is a general purpose language and b) it is immediately familiar to programmers who have used Pascal, Modula-2, and Oberon. Most Pascal programs from the domain of algorithms and data structures are successfully compiled by the Zonnon

compiler In computing, a compiler is a computer program that translates computer code written in one programming language (the ''source'' language) into another language (the ''target'' language). The name "compiler" is primarily used for programs that ...

programming in the large In software engineering, programming in the large and programming in the small refer to two different aspects of writing software, namely, designing a larger system as a composition of smaller parts, and creating those smaller parts by writing li ...

'', Zonnon is much more elaborate compared to its predecessors. Zonnon has four different kinds of program units: objects, modules, definitions, and implementations. The first two are instantiated at runtime, the third is a

unit of abstraction, and the fourth is a unit of composition. Here is a brief characterization: *

s, operators, and structural units of the runtime environment. In combination with the import relation, the module construct is a powerful system structuring tool. * Definition is an abstract view on an object (or on a module) from a certain perspective. It is a facet of the object or, in other words, an abstract presentation of one or more of its services. * Implementation typically provides a possibly partial default implementation of the corresponding definition. It is a unit of reuse and composition that is aggregated into the state space of an object (or module), either at compile time or at runtime.

Compositional model

Zonnon uses a compositional inheritance model based on aggregation. Typically, an object (or module) is composed of several functional components, each of them presenting itself to clients in the form of an abstract definition. The set of definitions plus the object’s intrinsic interface (that is the set of all public elements of the object) constitutes the interface between the object and its clients.

Concurrency model

Zonnon allows adding behavior to objects (and modules). For this purpose, the notion of active object was imported from the Active Oberon language and generalized towards a unified model of hierarchic activities. Activities are encapsulated threads that come in two flavors: local activities and agent activities.

Local activities

Local activities express intrinsic object dynamics. A typical context is a block of statements representing the “launch logic” for a set of mutually independent activities, with the assumption that the end of the block acts as a barrier that cannot be passed before all activities have terminated.

Agent activities

Agent activities control the interoperability of objects in terms of formal dialogs. Each agent activity within a “callee” object serves as a template of a formal dialog between some caller and the callee. Agent activities typically implement a parser for some predefined syntax that constitutes a kind of contract between the two communication partners. Formal dialogs are a generalization of asynchronous method calls. This is reflected in the form of a syntax that is borrowed from ordinary method calls.
