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");
/ ]5 e9 I0 s! \+ Q4 h' B, g  treenode thesum = getvarnode(current,"targetcomponentsum");
  setnodenum(thesum,0);

; q7 `4 |" Y% x, c% f6 ]   {
     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
    inc(thesum,getlabelnum(first(current),"1"));
& ~$ C  i% d6 M- P) L. s$ @     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
1 d& y1 D; Y. J- h; T    inc(thesum,getlabelnum(first(current),"2"));
7 o. W( F' E! f     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
    inc(thesum,getlabelnum(first(current),"3"));
. f' ~" E) F, I/ f" Z1 b$ G7 I     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
" r7 U: z4 ]) o* X( K    inc(thesum,getlabelnum(first(current),"4"));
  }
8 q6 G% g5 k1 W* p/ v4 e/ R" z( 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
