java - 限制对特定类的方法调用(在接口(interface)范围内)

Question

有没有办法创建一个限制访问特定方法的接口(interface)？

示例:

public interface MyInterface {

    /*
     * I want to restrict access to this(and only this) method so only 1 specific class 
     * can call it. Is there a way of doing that? 
     */
    public void setComponent(Component);

    ...other methods...

}

编辑:

类似于:

public default void setComponent(Component component) {
    StackTraceElement[] stacktrace = Thread.currentThread().getStackTrace();
    if(!stacktrace[1].getClassName().equals("MyClassName")){
        throw new IllegalStateException("Method should not be called explicitly");
    }
}

可能可以解决问题，但稍后会被覆盖，因此这不会真正解决问题。

Answer 1

答案是否。因为默认情况下，Interface 中的方法是公共(public)的。如果要实现，请创建Abstract类并将方法声明为protected:

public abstract class MyAbstractClass {


    protected void setComponent(Component);

    ...other methods...

}
