描述----------Description----------
This function loops over the elements of a StringSet and evaluates the specified function on each value. Since the StringSet-class is an opaque, internal data structure of the libstree library, this method takes care of handling the details of the iteration.
此功能循环以上的StringSet元素和评估每个值指定的函数。自StringSet-class是一个不透明的内部数据结构的libstree库,这种方法需要迭代的细节处理。
方法----------Methods----------
the first argument is the StringSet-class whose elements are to be processed sequentially. The second argument is a function which is called for each element. The argument to this function is the string from that element of the string set.
第一个参数是StringSet-class,其元素是顺序处理。第二个参数是一个为每个元素调用函数。这个函数的参数是从该元素的字符串集的字符串。
