如何使用示例
下面的示例创建一个名为 Plant 的类。Plant 构造函数采用两个参数。
// Filename Plant.as
package {
public class Plant {
// Define property names and types
private var _leafType:String;
private var _bloomSeason:String;
// Following line is constructor
// because it has the same name as the class
public function Plant(param_leafType:String, param_bloomSeason:String) { // Assign passed values to properties when new Plant object is created _leafType = param_leafType;
_bloomSeason = param_bloomSeason;
}
// Create methods to return property values, because best practice // recommends against directly referencing a property of a class public function get leafType():String {
return _leafType;
}
public function get bloomSeason():String {
return _bloomSeason;
}
}
}
在脚本中，使用 new 运算符来创建一个 Plant 对象。
var pineTree:Plant = new Plant("Evergreen", "N/A");
// Confirm parameters were passed correctly
trace(pineTree.leafType);
trace(pineTree.bloomSeason);
