oop - ColdFusion 9 CFScript 私有(private)属性和公共(public)属性

Question

有没有办法让 isDevMode、devModeToEmailAddress、devModeFromEmailAddress 成为私有(private)属性？

代码:

/**
* email
* @accessors true
*/
component email output="false" hint="This is email object." {

/* properties */
property name="toEmailAddress"   type="string";
property name="fromEmailAddress" type="string";
property name="subject"          type="string";
property name="body"             type="string";
property name="attachments"      type="array";

/*
private isDevMode
private devModeToEmailAddress
private devModeFromEmailAddress
*/

}

Answer 1

您可以添加 setter="false" 和 getter="false" 来防止 getter 和 setter，但您不能直接限制对属性的访问。最好的办法是将它们放入组件本地范围内的构造函数中。

/**
* email
* @accessors true
*/
component email output="false" hint="This is email object." {

isDevMode = false;
devModeToEmailAddress = "foo@foo.com";
devModeFromEmailAddress = "bar@foo.com";

/* properties */
property name="toEmailAddress"   type="string";
property name="fromEmailAddress" type="string";
property name="subject"          type="string";
property name="body"             type="string";
property name="attachments"      type="array";


}

然后，当您需要使用它们时，只需在任何函数中引用 variables.isDevMode 即可获取值。如果您需要在运行时设置它们，您可以在函数的 init() 方法中设置它们。我通常这样做:

component email output="false" hint="This is email object." {

    instance = {};

    /* properties */
    property name="toEmailAddress"   type="string";
    property name="fromEmailAddress" type="string";
    property name="subject"          type="string";
    property name="body"             type="string";
    property name="attachments"      type="array";


    public email function(required boolean isDevMode, required string devModeToEmailAddress, required string devModeFromEmailAddress){

        variables.Instance.isDevMode = Arguments.isDevMode;
        variables.Instance.devModeToEmailAddress = Arguments.devModeToEmailAddress;
        variables.Instance.devModeFromEmailAddress = Arguments.devModeFromEmailAddress;

    {

}

然后，只要我需要这些值，我就可以得到 variables.Instance.isDevMode。我还创建了一个通用的 get() 方法，它将返回 variables.instance，这样我就可以看到里面有什么。

public struct function get(){
    return Duplicate(variables.Instance);
}

但是因为它们在组件局部变量范围内，所以不能从组件外部修改它们。
