scala 中是否有一种语法或方法可以访问 case 语句中的整个匹配结构？
澄清一下，如果有“as”关键字，可以这样做:
x match {
case Y(z) as matched =>
// do stuff both with "matched" and "z" here ...
...
}
最佳答案
您应该能够使用@ 语法:
x match {
case matched @ Y(z) =>
// do stuff both with "matched" and "z" here ...
...
}

关于Scala，如何访问整个匹配项 : X match {case Y(z) as matched =>，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17982421/
