1.0 Contents

FileManager contains five Directory Navigators. They all do the same thing in different ways:

DirExplorer-Naive:
Searches a directory tree rooted at a specified path for files matching specified patterns, e.g., *.h, *.cpp, *.cs, ... It is a naive implementation in that application specific processing has to be inserted into its doFile and doDir methods.
DirExplorer-Template:
Same functionality as Naive, but the doFile and doDir methods are specified by a class App, passed as a template parameter, so the file manager doesn't need to change for each application.
DirExplorer-Inheritance:
Same functionality, but now doFile and doDir are virtual methods that an application overrides.
DirExplorer-Events:
Same functionality, but implemented with the "Command Pattern". Multiple parts of an application can subscribe for notification of file and directory discovery.
DirExplorer-Provider:
Uses a provider plug-in model. That's more powerful, but also more complex that the other designs.

I built these to demonstrate design techniques for CSE687 - Object Oriented Design, at Syracuse University. I usually use DirExplorer-Template, for my own projects, as it is the simplest and easiest to use of the reusable file manager components.

2.0 Build

These projects were built with Visual Studio Community Edition - 2019, and tested on Windows 10.
