Benoit Wiart created FLEX-33893:
-----------------------------------
Summary: CSSStyleDeclaration is inefficient during style matching
Key: FLEX-33893
URL: https://issues.apache.org/jira/browse/FLEX-33893
Project: Apache Flex
Issue Type: Improvement
Components: Mobile: Performance, Performance: Framework, Styles
Affects Versions: Apache Flex 4.11.0
Environment: desktop mobile
Reporter: Benoit Wiart
When no factory (or defaultFactory) is provided a new function is created when
matching styles (addFactoryAndOverrideStylesToProtoChain, addStyleToProtoChain,
applyFilter).
This is a major source of unneeded memory allocations (== GC)
The patch re-use a single function as the prototype is always reseted
This should be reviewed by an actionscript ninja ;-)
