[CDO][0.8.0] CDORevision List - should have a better implementation for UNINITIALIZED data. [message #106226] Sat, 05 January 2008 14:46 Go to next message

Hi EIke,

Do you think it will be good to have a List that have a better management of
UNINITIALIZED value ?

At the moment, if the real size of a collection is 1000, we create an array
of 1000, we initialized a few of them... after we put the other element at
UNINITIALIZED.


Should the list have better management ? We could beneficiate with a better
management internally.

- Improve serialization
- Improve memory

Thank you

Simon

Also it will optimized CDOReferenceProxyImpl... we should not initialize all
the index with that.

Maybe we should have something to start with as easy as the following :

If I want to load a list with size 1000 with no data initialized inside...
we should not allocate the array or any CDOReferenceProxyImpl
As soon as the application initialize something we can go like before.
This will be a good start it will:
- Abstract any details about how to manager the list internally.

It will be easier to optimize after that.

Simon,

I fully agree. Please open an enhancement request. I'd appreciate if
you'd come up with an initial patch ;-)
