我知道<IfModule mod_rewrite.c> <IfModule mod_negotiation.c> Options -MultiViews -Indexes </IfModule> RewriteEngine On # Handle Authorization Header RewriteCond %{HTTP:Authorization} . RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] # Redirect Trailing Slashes If Not A Folder... RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} (.+)/$ RewriteRule ^ %1 [L,R=301] # Handle Front Controller... RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L] </IfModule> 在方法或类变量的上下文中意味着什么,但它在顶级类的上下文中意味着什么?是否与private[this]相同,private[package]关键字替换当前包的名称?

答案 0 :(得分:0)

class Stock{
 private var price: Double
 def isHigh(that: Stock): Boolean =  this.price > that.price
}

这里是访问私有价格变量的外部对象,但是如果我们定义

private[this] var price: Double

就这样无法获得价格
