求教！哪位大神给我讲解一下这一串代码是什么意思？新手上路，很着急！！！！！！！

treenode thelist = getvarnode(current,"componentlist");
: N! _# P1 |2 v4 Q8 E0 J; J  treenode thesum = getvarnode(current,"targetcomponentsum");
  setnodenum(thesum,0);

   {
* S! P' X7 W* P( S/ f/ j1 N& u0 Z/ b     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
2 F  t9 {/ d1 G7 s( l( f    inc(thesum,getlabelnum(first(current),"1"));
     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
. p! {. t5 F* k- |% `    inc(thesum,getlabelnum(first(current),"2"));
+ ^5 ~+ S' C. G, L% i9 |     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));

我这新手，主要是不明白  setnodenum 、getlabelnum这之类的具体什么含义，有什么作用

你的代码不全啊，但是大概就是根据当前实体的标签值设置属性节点“componentlist”（好像是个表格）的值，，然后将节点targetcomponentsum的值加対应标签的值。
