AS3的語法是什么？ 新 <object> [];

Question

我正在嘗試在舊的Flex 3.6項目中使用SoundAS庫。 但是，在嘗試使用它時，出現了一些語法錯誤。

在SoundManager.as中查看，報告的語法錯誤不是實際的問題。 相反，所有錯誤似乎都是由使用諸如new <Object>[];類的東西引起的new <Object>[]; ...例如， if(!groups){ groups = new <SoundManager>[]; } if(!groups){ groups = new <SoundManager>[]; }在第350行。

我不熟悉所使用的語法...它想做什么，為什么它不能在Flash Builder 4.7中工作，如何使它工作？

是的，@ AndreyPopov是正確的。 此變量groups是SoundManager類型的Vector 。 var groups:Vector.<SoundManager>相應的if語句if to groups實例為null ，如果是，則創建一個新實例。
