some questions
Hi all:
I read the document about
Pool Service
Global Cache Service
Factory Service
Pull Service
I have some questions:
1. Pool Service v.s. Factory Service
It seems they are all used to generator Runtime Classes and all have an repository to store the already generated class to improve performance.
Which one is recommented?
2. Integrate Factory Service and Pool Service
The document mentioned the integration. Can any one explain a little more about this?
3. Global Cache Service and Pool Service
Since we can store any thing in Global Cache, can I store the already generated class in Globle Cache instead of using Pool Service.
4. The Pull Service
I know that using Pull service, we can easily get information in VM. But what is the benifit for java classes using Pull service. Can I using Global level Pool Service, or Global Cache Service instead.
Regards&Thanks
fanyun

The factory service only concerns itself with instantiating objects, it
does not pool them. The pool service uses the factory code to
instantiate new objects, if the pool is exhausted.

see above.

why? the cache works using keys to retrieve objects, what are you going
to use for your keys? And if you have a good answer for that there are
several other reasons not to use a general cache as an object pool.

don't understand this question, do you have a code example?
