SearchDir

Object-Oriented Analysis and design class project for directory searching and difference comparison.

Basic Structure

• builderModel: Store file and directory model class.Both of the model class use Builder pattern.
• modeFactory: Store factory classes's codes,using Factory pattern here.
• decoratorFilter: Store codes related to condition search ,using Decorator pattern here.
• gui：Codes about gui.Here I'm using JavaFX to build the interface
• sortStrategy: Store codes related to sorting directory files according to some rules,using Strategy pattern here.

Design

• Use SFile to represent file object
• Use SDirectory to represent directory object
• Use FileListManager to store specific directory's files info,use Singleton pattern to avoid unneeded instance of this manager class.
• Use Sort interface，and let other sorting method implements it
• Use CondictionFilter interface，as ancient class of other condition filters
• Use ModeFactory，return objects that implement Mode interface.
• InfoGetter, get directory infos and make itself a decoratee,become capable to retrieve file infos filtered byCondiction

UML Design

Usage

• Run SearchGui for most of the functions with nice interface
• Or InfoGetter.main() for only search by some criterias

Running screenshots

Basic：

• Before Search

In log mode,you can search directories for result,but you can't use compare button.

• First Search

The output will show in left window.Of course you can choose whichever side of window you want by toggling the combobox "left/right"

• Second Search

Now that that directory you search on your disk has changed,it will show new infos at right window at default.

Till now,the program has automatically written info into logs.Now switch to compare mode:

Then click compare button on main screen,then you might see something like this:

Then we know some files were removed from original place.

If there is any new file added in,you can see the changes too in differ log

Extra and command mode

You can use other sorting method while searching for directories infos:

And you can search for some files with some condition under command line mode:

About：

What can it do?

• Normal mode:

  • Given a directory path,outputs all directories and files' info on gui.
  • Automatically save above infos into a log file.
  • Be able to choose sorting method through a combobox.
  • Read log files that are already exist through gui.
  • If enter the same path twice into search box to search infos, it will build a new.txt log file.
  • Entering different path to search in this mode won't build new log file(or can't update new log)

• Compare mode:

  • If info of searched dirs have changed on your machine,when in compare mode, it will generate a differ.txt file to show the old and new structure's difference
  • Make sure to have an old and new log file of same path first!(Otherwise compare will be meaningless)

• Command line mode(InfoGetter):

  • According to fileSize，fileType，fileLastEdit to search for matches and output in the console.

Noted

If you are confused about the comparison result,check the ori,new and differ log file.
