Hi,
I'm wondering why there are so many final methods in FSDirectory. In particular I'd like to customize the locking behaviour and was originally going to do that by subclassing FSDirectory and just overriding the makeLock() method, until I noticed that it was marked final.
I can't see any obvious reason for this. The usual motivation given is speed, but this article:
http://www-106.ibm.com/developerworks/java/library/j-jtp1029.html
... strongly implies that it doesn't make much difference at all, and the opinion of the writer is certainly that the losses outweigh the gains.
For now I'm just going to copy/paste the FSDirectory class into my program and customize it there. If speed is the motivation, does anybody have benchmarks to show that it really speeds things up?
thanks -mike
