实例化嵌套类Scala中延伸时的Java类

Question

我

有抽象的Java类，它包含声明为protected static嵌套类：

public abstract class AbstractJavaClass { 
    // contains nested class 
    protected static class InnerClass { 
    ... 
    } 
} 

当我试图实例它延长AbstractJavaClass就像我在做的java类斯卡拉（即单指内法新名称将InnerClass）：

class ScalaClass extends AbstractJavaClass { 
    def method = new InnerClass() 
} 

我得到错误：类型是将InnerClass不ScalaClass的成员。我究竟做错了什么？在Java中相同的工作正常。

Answer 1

迷迷糊糊的位置：access java base class's static member in scala

它说

This isn't possible in Scala. Since Scala has no notation of static you can't 
access protected static members of a parent class. This is a known limitation. 

虽然我无法解析初始发行（当类是protected static），当我定义它改为public static的AbstractJavaClass我可以用它这样：

class ScalaClass extends AbstractJavaClass { 
    import AbstractJavaClass.InnerClass 

    def method = new InnerClass 
} 

使用new InnerClass没有导入给出同样的错误。
