Justin Mclean updated FLEX-33386:
---------------------------------
Labels: Performance easyfix (was: Performance)
> Style Declaration Matching Tuning - Inlining
> --------------------------------------------
>
> Key: FLEX-33386
> URL: https://issues.apache.org/jira/browse/FLEX-33386
> Project: Apache Flex
> Issue Type: Improvement
> Components: Styles
> Reporter: RJ Camarillo
> Assignee: Frédéric THOMAS
> Priority: Minor
> Labels: Performance, easyfix
> Fix For: Adobe Flex SDK Next
>
> Attachments: mx.styles - inlined.zip
>
>
> One of the most executed calls during the lifetime of a Flex UIComponent is
> the matching of style declarations (i.e. state change, component
> initialization, etc).
> As such, it is one that the community has monkey-patched often in order to
> attain speed-ups even for just a little.
> This is one of the improvements done to achieve that end. Instead of doing
> method calls to the different style classes (i.e. CSSCondition, CSSSelector,
> CSSStyleDeclaration), the StyleProtoChain class has been modified to perform
> matching inline as much as possible.
> The implementation is not perfect and I'm sure it can be improved further
> with the help of the bigger community. For example, the
> matchingDecls.sortOn("selectorIndex", Array.NUMERIC) call could be improve to
> use one of the faster sort algorithms out there. There are also some methods
> calls that are not inlined.
