[lang] Adding a Memoizer class
Hello All,
I am currently using a class like the Memoizer class [1] from "Java
Concurrency in Practice" [2], a great book.
It would fit perfectly in org.apache.commons.lang3.concurrent.
Any thoughts for or against?
Thank you,
Gary

Hi Gary,
even if I'm not active on Lang, I'm very +1 for introducing this
feature, looks a great addition!!!
Have a nice day, all the best!

I would recommend staying with the standard name. Why invent yet another
term for a well-known concept:

Hi All:
I had a simple case to implement and using MapMaker was better that
the Memoizer I wrote. Just to flush (pun intended) things out with
some basic APIs like your flush() example quickly grows into a
MapMaker... I do not see the use case for a super simple MapMaker,
like something between a Java's ConcurrentHashMap and Guava's
MapMaker. I urge us to consider real use cases before adding this (I
know, I know, I am the one who proposed it.)

Yes, the name is a little obscure but describes the pattern correctly.
We could call it CacheSomething (the next release of Guava will have a
CacheBuilder class.)
The name will definitively reflect the usage POV but should not
present the class in a restricted way. Map is more general than Cache
for example.

Gary

Just had a short glance on the API of MapMaker. My impression is that it
is out of scope for [lang] as it is a full blown collection with many
sophisticated features.
Compared to this a Memoizer is a pretty simplistic component, but it may
nevertheless be useful for some cases. It could be slightly extended,
e.g. by providing a flush() operation.
And I would recommend another name. At least for me as non-native
speaker it is hard to imagine what a Memoizer is supposed to do. I would
probably use something with "Cache" in its name.

Good question. It would not be a char for char copy but the pattern
would be the same. I'll look around...
