public Group(Node... children)

其他例如：

public KeyFrame(Duration time,keyvalue... values)

我发现…意味着我应该将java数组传递给方法,所以我一直在做这样的事情,

(-> timeline .getKeyFrames 
  (.addAll 
    (into-array [(KeyFrame. blabla) (KeyFrame. blabla)]))`

每次有一个var arg时,必须要做(into-array …)是很烦人的,当var arg是我实际传入的基类时,它会更烦人.例如

(Group. (into-array [(Circle. 100) (Rectangle. 100 100)]))

导致类型不匹配错误.相反,我必须这样做：

(Group. (into-array Node [(Circle. 100) (Rectangle. 100 100)]))

所以我做了这个功能：

(defn make-group [& items]
  (Group. (into-array Node items)))

哪个适用于群组,但不能解决一般问题.

那么有没有一种解决省略号/变量问题的好方法,所以我不必为每个vararg方法创建特殊函数？这个函数的要求是它需要你想要调用的方法(例如Group),固定的args,var args,并且在某种程度上,函数会知道如何找到var args中元素的公共基类.
