是否有可能存储阵列到EncryptedLocalStore项目？空气 [英] Is it possible to store an Array into an EncryptedLocalStore item? AIR

问题描述

我要救我的数组的strucure并加载它下一次我打开我的AIR应用程序。有没有办法将其存储到EncryptedLocalStore项目，然后得到它后，当我重新打开应用程序？

I want to save my Array's strucure and load it the next time I open my AIR application. Is there a way to store it to an EncryptedLocalStore item then get it later when I re-open the app?

推荐答案

EncryptedLocalStorage.setItem（）方法需要一个字节数组。为了存储阵列，只是使用ByteArray.writeObject（）方法（如<一个描述href="http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/utils/ByteArray.html#writeObject" rel="nofollow">http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/utils/ByteArray.html#writeObject())你的数组转换为ByteArray - 然后坚持相同的ELS

EncryptedLocalStorage.setItem() method takes a byte array when storing contents. To store an array, just use ByteArray.writeObject() method (as described in http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/utils/ByteArray.html#writeObject()) to convert your Array to a ByteArray - and then persist the same to the ELS.

var array:Array = getArray();
var byteArray:ByteArray = new ByteArray();
byteArray.writeObject(array);
EncryptedLocalStorage.setItem('somekey', byteArray);

希望这有助于。

Hope this helps.

更新：增加了code检索阵列背

Update: Added code to retrieve the array back.

var byteArray:ByteArray = EncryptedLocalStorage.getItem('somekey');
var array:Array = byteArray.readObject() as Array;

更新：对于定制类

Update: For custom classes.

在你想自己的自定义类序列化到ByteArray的情况下，您可能需要调用registerClassAlias​​（）写对象则ByteArray之前。对于如：

In case you want to serialize your own custom classes to the ByteArray, you may have to call registerClassAlias() before writing the object to the ByteArray. For eg.

registerClassAlias("com.example.eg", ExampleClass);
