Every time I read about using synchronized in Scala the author will usually mention that Actors should be used instead (this for example). While I understand roughly how actors work I’d really like to see an example of Actors being used to replace Java’s synchronized method modifier (by this I mean its Scala equivalent – the synchronized block) in a piece of code. Modifying the internals of a data structure for instance would be nice to see.
Is this a good use of Actors or have I been misinformed?
Actors guarantee that only a single message will be handles at time so that there will not be two threads accessing any of the instance members – ergo no need to use synchronized
