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");
3 j, Z* S$ E# [6 @3 U* A  setnodenum(thesum,0);

   {
# A0 j8 t; U7 A! G# z/ {7 X     setnodenum(cellrowcolumn(thelist,1,1),getlabelnum(first(current),"1"));
    inc(thesum,getlabelnum(first(current),"1"));
, L( t& x0 m+ X. E. {     setnodenum(cellrowcolumn(thelist,2,1),getlabelnum(first(current),"2"));
    inc(thesum,getlabelnum(first(current),"2"));
: Y: Q$ h& z; g2 J; z$ X& o     setnodenum(cellrowcolumn(thelist,3,1),getlabelnum(first(current),"3"));
  V% R, h5 ^  X8 r4 ^0 s3 u    inc(thesum,getlabelnum(first(current),"3"));
     setnodenum(cellrowcolumn(thelist,4,1),getlabelnum(first(current),"4"));
3 L# [+ }/ X& k! Q  b! \0 U    inc(thesum,getlabelnum(first(current),"4"));
- @, L/ g' T2 T# x- @  }
}

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
