Introduction

Dflow software essentially has three parts: user interface, scheduler and parser. The user interface allows the user to define a dataflow. The classes for user interface derive from FLTK base classes. The schedule schedules the computation of the dataflow. The parser reads (and writes) the dataflow graph from ( to ) a file ie it provides load/save functionality.

Inter module coupling

The coupling between all modules is data coupling except for that between ModuleGraph and ModuleButton which is common coupling.
