Hi,

Groovy recently added a new feature to its closures - memoization - as a performance optimization.

Thanks for sharing!

Roshan, haven't been following GPars as well as I should have; but, I believe GParsPool makes memoizations thread-safe. Do those guarantees hold in the Groovy port?

Hi Saager,

I don't think so, but then I am not an expert in GPars myself. Why don't you bring it up on the main groovy mailing list?

I am sure Vaclav will be happy to clarify it - having done both memoize() implementation in GPars as well as its port to Groovy

yeah, i need to get back on the groovy-dev and groovy-user lists; it'll have to wait for the weekend
a quick look at the code seemed to indicate that it wasn't really thread safe, java.util.concurrent.ConcurrentHashMap doesn't lock for retrievals
