如何清空可变图(由val定义)？

Question

我为我的对象定义了一个可变属性

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

看看api文档吧!

myMap.clear
