./plus/list.php - 动态展示栏目列表页(也可能是频道封面)

arc.listview.class.php 是dedecms的列表页的相关处理类

__construct() // 初始化一些字段，变量
CountRecord() // 统计列表记录，总条目数，每页条目数，并对列表模板进行解析
MakeHtml() // 创建列表页HTML，主要是后台批量生成
Display() // 解析并展示列表页
MakePartTemplets() // 创建 ‘频道封面‘，或得到 ‘外部链接‘ 目录
DisplayPartTemplets() // 同上，只是直接展示，不生成
ParseTempletsFirst() // 只解析模板中的 include/taglib/* 固定标签
ParseDMFields() // 解析模板中的动态字段(list, pagelist, field标签解析)
GetArcList() // 获取展示列表详情
GetPageListST() // 获取静态分页导航

GetPageListDM() // 获取动态分页导航(当列表页是动态页，分页自然也得使用动态链接)

查看了文件的主要源码，进行了注释，就整个文件黏贴过来了。列表页详情，分页导航方法等方法未做注释
