我需要在Adobe Air中創建XML日誌文件。我的第一個想法是使用某種自動化的序列化。我找到了FlexXB庫。我創建了簡單的記錄並標記通過以下方式在Adobe Air中創建XML日誌需要一些幫助
package loggingTools
{
[XmlClass]
[ConstructorArg(reference="timeStamp")]
[ConstructorArg(reference="item")]
[ConstructorArg(reference="action")]
[ConstructorArg(reference="arguments")]
[ConstructorArg(reference="success")]
[Bindable]
public class MessageAction
{
[XmlAttribute()]
public var timeStamp:Date;
[XmlAttribute()]
public var item:String;
[XmlAttribute()]
public var action:String;
[XmlAttribute()]
public var arguments:String;
[XmlAttribute()]
public var success:Boolean;
public function MessageAction(timeStamp:Date, item:String, action:String, arguments:String, success:Boolean) {
this.timeStamp = timeStamp;
this.item = item;
this.action = action;
this.arguments = arguments;
this.success = success;
}
}
我試圖序列化一個對象與註釋類：
public class PlainXMLLogger
{
//private static var isStarted:Boolean;
private var logFile:XML;
[XmlArray(alias = "Log", type="loggingTools.MessageAction")]
[ArrayElementType("loggingTools.MessageAction")]
public var messages:Array;
public function addMessageAction(item:String, action:String, arguments:String, success:Boolean):void {
var newMessageAction:MessageAction;
newMessageAction = new MessageAction(new Date(), item, action, arguments, success);
messages.push(newMessageAction);
}
public function close():void {
var logXML:XML = FlexXBEngine.instance.serialize(messages);
trace(">> XML LOG ");
trace(logXML.toString());
}
}
現在，系列化產生一個錯誤： 類型錯誤：錯誤＃1009：無法訪問空對象引用的屬性或方法。 在com.googlecode.flexxb.core :: SerializationCore /序列化（）
當然，我可以序列中的所有物件收集一個接一個，但我認爲，這是一個壞主意。
