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");
  `2 ]% d6 R4 F, q. Q1 `/ y, ~/ D  setnodenum(thesum,0);
5 [( W7 c5 p3 T9 u4 t
* g4 K! R7 Z1 B1 y# s   {
7 v: `& G( b9 @' ]0 C: _     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
) g7 Q/ W2 c: e9 L8 t3 h    inc(thesum,getlabelnum(first(current),"1"));
     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
. F2 y' H4 s6 G, b: T    inc(thesum,getlabelnum(first(current),"2"));
     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
! y# O- T) N' [- e/ a6 `1 i$ u, C$ J* j    inc(thesum,getlabelnum(first(current),"3"));
0 ]. Y( p; E3 ?     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
    inc(thesum,getlabelnum(first(current),"4"));
/ p0 ^1 @8 R; e$ x+ [0 z  }
, B: @1 o9 d# ?8 \$ i}

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。

% p) }% R1 z; l6 B) Y% y# Z/ ]. A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
