------------------------------------------
Summary: Potential for performance improvements in
ListCollectionView.addAll/addAllAt
Key: FLEX-34942
URL: https://issues.apache.org/jira/browse/FLEX-34942
Project: Apache Flex
Issue Type: Improvement
Components: Collections
Reporter: Gareth Daniel Smith
Priority: Minor
The performance of ListCollectionView.addAll could be improved in the case
where there is no sort/filter. Currently, in this case, one event is emitted
per added row, but AFAICT there only needs to be a single event emitted (that
would contain all the new rows).
This would improve performance a lot where there are grids/lists that are bound
to ListCollectionView/ArrayCollection instances that get updated, which is a
common use-case in my experience.
On a related note, please consider my pull request here:
https://github.com/apache/flex-sdk/pull/18 - as this would alllow me to move
away from ArrayCollection towards ArrayList without creating bugs that won't be
detectable until runtime.
