Why does Flex's ArrayCollection's Contain method look at memory reference?

由 倾然丶 夕夏残阳落幕 提交于 2019-12-03 16:10:29
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? Couldn't you just extend ArrayCollection and override the contains() method? Alternatively you can paste the source for ArrayCollection

I have a Flex question, which isn't as easy as it seems at first. At least I'm struggling since 1 week with it. I have prepared a test case and a screenshot. The question is: how do you merge data (coming repeatedly from server) into a filtered ArrayCollection? The screenshot: The TestCase.mxml (just place it into a Flash Builder 4.6 project): <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"> <fx:Declarations> <s:RadioButtonGroup id="_group" itemClick="radioClicked(event);"/> </fx:Declarations> <fx:Script

Is there any convenience method that allows me to concatenate two Doctrine ArrayCollection() ? something like: $collection1 = new ArrayCollection(); $collection2 = new ArrayCollection(); $collection1->add($obj1); $collection1->add($obj2); $collection1->add($obj3); $collection2->add($obj4); $collection2->add($obj5); $collection2->add($obj6); $collection1->concat($collection2); // $collection1 now contains {$obj1, $obj2, $obj3, $obj4, $obj5, $obj6 } I just want to know if I can save me iterating over the 2nd collection and adding each element one by one to the 1st collection. Thanks! Better (and

Doctrine 2 ArrayCollection filter method

Can I filter out results from an arrayCollection in Doctrine 2 while using lazy loading? For example, // users = ArrayCollection with User entities containing an "active" property $customer->users->filter('active' => TRUE)->first() It's unclear for me how the filter method is actually used. FredRoger The Boris Guéry answer's at this post, may help you: Doctrine 2, query inside entities $idsToFilter = array(1,2,3,4); $member->getComments()->filter( function($entry) use ($idsToFilter) { return in_array($entry->getId(), $idsToFilter); } ); Ryan Doctrine now has Criteria which offers a single API
