How to read a continuously updated log file in scala

Question

I want to read a continuously updated file as (tail -f) in scala, I can't use other tools such as tail because I need to do some extra processing on the records.

So how to keep track of exact file contents every time.

Answer 1

There's an implementation of "tail -f" in Apache commons. http://commons.apache.org/proper/commons-io/javadocs/api-release/org/apache/commons/io/input/Tailer.html
With google search, I found another implementation of "tail -f": https://github.com/alaz/tailf/blob/master/src/main/scala/com/osinka/tailf/Tail.scala
