The RooRefCountList is only kept for IO backwards compatibility. From an IO point of view, it is equivalent to its parent class, theRooLinkedList. So we don't need to keep all the member function implementations. IN the one place where therefCount()member function is used in IO schema ev...

Python99 P101: Find the last element of a list 求列表中最后一个元素 求列表中最后一个元素。用单元测试描述为: Python内建的list是有序序列,其中每个元素都可以通过位置索引直接访问。且Python内建了函数len,用读取任意有序序列的长度。先用len读取list的长度,将长度减去一即为末尾元素的位置索引。 位置索引...
