获取分组树

参数:

list - 需要分组的数据

mapper - 数据映射器

lastMapper - 最后分组数据映射器

lastCollector - 最后分组数据收集器

classifiers - 分组函数集

public static <T extends TreeNode<T>> void sort(List<T> nodes,
                                                Comparator<T> comparator)

排序分组树

merge

public static <T extends TreeNode<T>> List<T> merge(List<T> nodes,
                                                    List<T> otherNodes,
                                                    BiFunction<T,T,T> merger)
