问题 I have an ArrayCollection that I'd like to sort by date and then time (in case there's two items with the same date). I've got it sorting by date fine (YYYY/MM/DD) but I can't figure out the time bit, time is in 24 hour format so the code would be basically the same as for the date. This is the code I used for the date sorting, it works fine. import mx.collections.SortField; import mx.collections.Sort; private function sort():void { var dataSortField:SortField = new SortField(); dataSortField

问题 I have an ArrayCollection of Objects. Each Object has the following keys/values: {date: 2009-12-01, visits=13555, bouceRate=45} {date: 2009-12-05, visits=46955, bouceRate=45} {date: 2009-12-06, visits=13685, bouceRate=45} {date: 2009-12-02, visits=13685, bouceRate=45} {date: 2009-12-04, visits=68755, bouceRate=45} {date: 2009-12-03, visits=35875, bouceRate=45} I need to sort this ArrayCollection by date, so it would be from past to present - like so: {date: 2009-12-01, visits=13555, bouceRate

问题 When using .contains() on an ArrayCollection in Flex, it will always look at the memory reference. It does not appear to look at an .equals() method or .toString() method or anything overridable. Instead, I need to loop through the ArrayCollection every time and check each individual item until I find what I'm looking for. Does anyone know why Flex/ActionScript was made this way? Why not provide a way from people to use the contains() method the way they want? 回答1: Couldn't you just extend

问题 since I'm quite new to Symfony and Doctrine I got a maybe stupid question ;-) Can someone use simple words to explain Collections (especially ArrayCollections in entities) to me? What is it and when and how to use them? (Maybe in an simple example) Couldn't figure it out quite well in the docs... Thanks in advance. 回答1: So the ArrayCollection is a simple class that implements Countable , IteratorAggregate , ArrayAccess SPL interfaces, and the interface Selectable made by Benjamin Eberlei .

问题 is there any way to use ArrayCollection (from mx.collections.*) in Flash CS3/4/5? How? 回答1: Not sure if you can use the Flex libs in Flash. For collections in AS3, though, check out this open source project. It rocks. 回答2: This question was asked before. It seems that there is: How can I use ArrayCollection like feature in ActionScript 3.0 Flash IDE? 来源： https://stackoverflow.com/questions/4333065/use-arraycollection-in-flash-cs5

问题 Basically I have been using a Dictionary object in my program that basically took ints as its keys and stored RTMFP peer IDs in the appropriate locations. Each int was unique and represented one user. Now I'm needing to expand on this where users are identified by a combination of the int and a Boolean value, kind of like this: private var m_iUID:int; private var m_blnIsCurrent:Boolean; Only the combination between those two really uniquely identifies the user. That being said I was just
