Overview

This project is using java 7 SDK (WatchService) for watching a given source directory. Each file or directory that is added to source directory is moved to a given target directory with the following rules applied:

• Text files are moved as they are
• All other files are renamed by adding the current unix timestamp to the end of the file

Main Classes

• DirectoryWatcherController - exposes two APIs: startListen and stopListen
• DirectoryWatcherService - handling registration to watched source directory
• DirectoryWatcherHandler - using WatchService class for registering to source directory and spawning a thread for processing incoming events
• EventCreateHandler - handles the "create" event, moving files to target directory
• StartServer - entry point for running a lightweight web server

Tests

• DirectoryWatcherHandlerTest - tests DirectoryWatcherHandler end to end
• EventCreateHandlerTest - tests EventCreateHandler class by covering the case in which a non text file is being moved (timestamp should be added)

API

• startListen GET (used instead of POST for simplicity)
  • srcDir e.g. /Users/Eyal/src
  • targetDir e.g. /Users/Eyal/target
• stopListen GET (used instead of POST for simplicity)
  • srcDir e.g. /Users/Eyal/src
