Title Body

I have a queue that processes objects in a while loop. They are added asynchronously somewhere.. like this: myqueue.pushback(String value); And they are processed like this: while(true) { String path = queue.pop(); if(process(path)) { Console.WriteLine("Good!"); } else { queue.pushback(path); } } Now, the thing is that I'd like to modify this to support a TTL-like (time to live) flag, so the file path would be added o more than n times. How could I do this, while keeping the bool process(String path) function signature? I don't want to modify that. I thought about holding a map, or a list that counts how many times the process function returned false for a path and drop the path from the list at the n-th return of false. I wonder how can this be done more dynamically, and preferably I'd like the TTL to automatically decrement itself at each new addition to the process. I hope I am not talking trash. Maybe using something like this class JobData { public string path; public short ttl; public static implicit operator String(JobData jobData) {jobData.ttl--; return jobData.path;} }
