Hi there
I’m building a little p2p program, so I want to make a file unable to be deleted while it is being downloaded. The simple solution is to use a lock, but then again I want it to be possible for multiple clients to download the file (meaning many thread can access the download method at the same time).
I hope the situation is clear.
any ideas of how to implement it?
Thanks!
Make use of java.util.concurrent.locks.ReentrantReadWriteLock. Use a java.util.concurrent.locks.ReentrantReadWriteLock.WriteLock fot the thread that is downloading the file and java.util.concurrent.locks.ReentrantReadWriteLock.ReadLock for the other threads that should access it while it its being downloaded.
