I am newbie to flex. I have a project at hand that required
handling huge amount of XML data. I get this data from remote
service and i connect using XMLsocket. Problem is after connecting
socket there are large number of data event at socket and UI freeze
during this time becoz i need all the data to populate some
Is there any other way of doing this... is there something
like threading in flex?
Flex uses FlashPlayer to interpret/run the code from SWF
files, the way this code gets executed is per frame.
Every frame some code gets executed and only per frame
nothing in between them. So if you parse your XML all at once this
means in one frame and if it takes longer than 1/FPS ( usually 24
fps) seconds than the client seems to be freezed.
If you can parse your data in chunks as they com on the
socket .. not all at once you can probably avoid the freeze.
Another way to do it would be to spread the XML parsing over
more frames ... it might take more time to parse the data, but the
client will not freeze.
With Flex components it is a bit tricky to do it, so I would
suggest you create a class that extends an Sprite so it can be
attached on the stage ... and than using the call later mechanism
to spread the process over as many frames as it takes, than issue
an event when the data is ready.
