我有这样的代码，我想将lambda表达式之一存储在某个对象中。

var opSpecBoolVal = false
val equalCheck = (x: Int, y: Int) => x == y
val greaterthanCheck = (x: Int, y: Int) => x > y
val lessthanCheck = (x: Int, y: Int) => x < y
val notEqualCheck = (x: Int, y: Int) => x != y

operatorType match {
   case "_equal" => opSpecBoolVal = false; exitCheck = equalCheck; 
   case "_greaterthan" => opSpecBoolVal = true; exitCheck = greaterthanCheck; 
   case "_lessthan" => opSpecBoolVal = false; exitCheck = lessthanCheck; 
   case …
