Maurice Amsellem commented on FLEX-33810:
-----------------------------------------
>From Alex Harui:
What was the test, just the call to describeType vs describeTypeJSON?
IIRC, the XML format is such that you may use the ".." expression to grab the
superclass's set of a particular thing of interest, and in JSON you can't so
you'd have to set up a loop to grab every <accessor> tag.
In looking at BindabilityInfo, it doesn't appear to use ".." so I think
switching here would be safe.
It may not be safe to change DescribeTypeCache. There might be other
third-party code relying on XML there.
Same for ObjectUtil, unless you can do it in a way that doesn't change the
output format.
And I haven't looked, but I'll bet most other places are pretty self-contained
and are safe to switch.
> Replace describeType by faster describeTypeJSON

>
> FP 10.1 has introduced new describeTypeJSON API that is roughly 3.5 times
> faster than previous describeType.
> describeType is still used in many places in the SDK.
> Since ApacheFlex is supporting FP 10.2 and higher, it should be beneficial in
> terms of speed to replace all occurrences of describeType by describeTypeJSON.
> {warning}
> Caution must be taken not to break the public APIs, that existing Flex apps
> maybe using.
