获得参数
' [9 U+ x" s0 J+ I( u/ p* W方法一：利用CATIDescendants 接口
CATIDescendants_var spDescendantsOnPart = spPrtPart;
/ r% \& A! S0 g7 d, c6 R* r0 {CATListValCATISpecObject_var spSpecObjects;
piDescendantsOnPart->GetAllChildren("CATICkeParm", spSpecObjects);
' j4 T! n- K7 p2 i5 n* Z) T方法二：利用CATIParmPublisher 中接口
CATIParmPublisher_var spParmPublisher = spPrtPart;
CATListValCATISpecObject_var ListFound;
spParmPublisher->GetAllChildren("CATICkeParm",ListFound);
方法三：利用CATContainer 中的ListMembersHere 方法
+ z& ~1 [" v% ~0 a3 `SEQUENCE(CATBaseUnknown_ptr) ListObj;
) J; R' l# h( N* ~+ J5 ^& Jlong NbObj = spContainer ->ListMembersHere("CATICkeParm",ListObj);
2 Z* Y' y6 X( Q" H, J3 O: `for(int j=0;j<NbObj;j++)//注意从0 开始
{
CATIAlias_var spAlias = ListObj[j];
cout<<spAlias->GetAlias()<<endl; //输出参数的名字
}
