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");
- b2 U* |! O7 H& U6 u/ p  setnodenum(thesum,0);

& I  W8 @6 u% t' _) H# r% H   {
     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"));
     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
    inc(thesum,getlabelnum(first(current),"3"));
2 P: j2 V: Z, T4 {7 B' f0 g# }     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
# s( S. c0 R& b    inc(thesum,getlabelnum(first(current),"4"));
; Y0 ~' Z; h8 ~9 M/ n  }
}

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。
