RJ Camarillo updated FLEX-33386:
--------------------------------
Description:
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.

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 things done to achieve that end. Instead of doing functional
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.
