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");
  treenode thesum = getvarnode(current,"targetcomponentsum");
/ A5 }; W+ |& f' ^; L! c  setnodenum(thesum,0);
9 X/ B5 s# R" k+ z
   {
, [- {4 A$ ~+ Q. e% A% ~3 a- g& s( V     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
    inc(thesum,getlabelnum(first(current),"1"));
2 ~4 ^) z0 @& X9 ~+ k     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
    inc(thesum,getlabelnum(first(current),"2"));
, O% U- u! v$ K/ u     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
8 e% n. }3 n, }6 \6 V    inc(thesum,getlabelnum(first(current),"3"));
/ f$ P) j( g" G& w  X* ]' p( H     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
( X5 O( H% G. [: |8 q2 M    inc(thesum,getlabelnum(first(current),"4"));
- Y/ u' H: q! ]0 ^  n- `, d5 l2 j  }
% @. e5 e  J$ e/ a! v7 x( {& h- w}

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。

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
