Populating the vbox in the right way
So here is my issue. I'm querying a third party application for 3 types of
data. To display it into a single timeline (holder), I combined all of the
data into an ArrayCollection which i then sort by date in descending order
(last date first). (see FUNCTION A)
Once that the ArrayCollection is built (on init at least), I then run it
through a loop and add it to a VBOX with a custom renderer (See FUNCTION B).
The custom renderer also performs some analysis of the information being passed.
Now to complicate matters, I'm querying the two different types of messages at
different interval (because of an overall cap in http request that can be
made). I don't have to worry about re-ordering based on the general messages
which are polled for every minute, but the direct messages are polled every 5
minutes. So conceivably in the timeline a sort needs to happen. Because of
the fact that operations need to happen and i want the user interface to be
acceptable, i don't want to redraw my entire timeline every time.
Looking for help in determining the best way to implement this process so that
messages that have appeared in the past can be "inserted" into the correct
position in the timeline (holder)
messages displayed in the timeline can be filtered (using arrayCollection
mainly for this)
Love the community's feedback especially if you've encountered a similar issue
in the past.
-FUNCTION A
private function displayTimelineHandler(tmlObj:TweetCommEvent):void {
trace(">>displayTimelineHandler");
var tempTml:Array = tmlObj.data as Array;
var j:int = this._mTimeline.length;
if (this._initFlag) {
// if the app is powering up just go ahead and
add the
for (var i:int=0;i<tempTml.length;i++) {
var obj:Tweet = new Tweet();
obj._itemID = tempTml[i].id;
obj._itemTitle =
tempTml[i].text;
obj._itemThumb =
tempTml[i].user.profileImageUrl;
obj._itemAuthor =
tempTml[i].user.screenName;
obj._timeStamp =
(tempTml[i].createdAt as Date).getTime();
obj._itemType = "timeline";
this._mTimeline.addItemAt(obj,
j);
j++;
}
}
}
--FUNCTION B
private function displayTimeline(timelineObject:TweetCommEvent):void
{
trace(">>displayTimeline");
//var timelineObjs:Array = timelineObject.data as Array;
var timelineObjs:ArrayCollection = new
ArrayCollection(timelineObject.data as Array);
var dateNow:Date = new Date();
var dateNowMS:Number = dateNow.getTime();
trace(">> " + timelineObjs.length);
tweetPanel.visible = false;
/* looping through the results here to decouple the
data format from display*/
for (var i:int=0;i<timelineObjs.length;i++) {
var newURL:String = new String();
var vbRenderer:VBoxSimpleRenderer = new
VBoxSimpleRenderer();
vbRenderer._itemID = timelineObjs[i].id;
vbRenderer._itemTitle =
timelineObjs[i].text;
vbRenderer.determineURL();
vbRenderer._itemThumb =
timelineObjs[i].user.profileImageUrl;
vbRenderer._itemAuthor =
timelineObjs[i].user.screenName;
vbRenderer.determineHowLong(timelineObjs[i].createdAt, dateNowMS);
holder.addChild(vbRenderer)
}
trace(ObjectUtil.toString(timelineObjs));
trace(">>displayTimeline 2");
}
