Groovy子类称为超类方法访问闭包 [英] Groovy subclass called superclass method that accesses closure

问题描述

我有一个groovy超类，看起来像：

I have a groovy superclass that looks like:

class AGroovyClass {
   private String str = "hello"
   void printString(int nTimes) {
     nTimes.times { println str } 
  }        
}

和子类

class AGroovySubclass extends AGroovyClass {
   // some other subclass methods
}

我的客户端代码调用：

new AGroovySubclass().printString(5)

这实际上打破了，因为它说，没有这样的属性str为AGroovySubclass

And this actually breaks because it says that that there is no such property "str" for AGroovySubclass

我会想，因为printString方法是在AGroovyClass，应该没有问题访问str属性，但显然我不正确。如果我想保持str私有，什么是使这个工作的适当方法？

I would have thought since the printString method is in AGroovyClass, it should have no problem accessing the "str" property, but clearly I am incorrect. If I wanted to keep "str" private, what is the appropriate way to make this work?

推荐答案

与私人访问修饰符。它工作如果你定义str保护。
http://jira.codehaus.org/browse/GROOVY-2433

It is an old bug with private access modifier. It works if you define str protected. http://jira.codehaus.org/browse/GROOVY-2433

编辑：你能避免关闭，使用for循环吗？不太酷，但工作原理：）

edit: Can you avoid closure, use a for loop instead? Not so cool, but works :)
