如何清空可變映射（由val定義）？

Question

我定義了一個可變屬性爲我的對象

object myobject{ 
    val myMap = mutable.Map[String,mutable.Set[String]] 
    def clear {// I don't know what code I must write here for remove all key Values on myMap} 
    def add(keyValue:(String,String)){//some code for add a keyValue to mymap} 
} 

Answer 1

已經在api docs看看！

myMap.clear
