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");
$ c- i1 R" D6 X' T0 b  treenode thesum = getvarnode(current,"targetcomponentsum");
2 ^5 H+ Y' H  X7 x/ n  k  setnodenum(thesum,0);
& x/ u. T* D! D0 L8 b
   {
" @3 L0 w$ t# Y, Q     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
    inc(thesum,getlabelnum(first(current),"1"));
     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
    inc(thesum,getlabelnum(first(current),"2"));
( b; A# y* }. D/ {& I5 v4 w     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
4 c4 \4 {! ^4 W2 Z+ A) f. O: G    inc(thesum,getlabelnum(first(current),"3"));
0 X! h& D3 l! \" j+ p/ y8 S     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
    inc(thesum,getlabelnum(first(current),"4"));
  }
0 y% \; \2 m7 u! }}

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
