- b/ k( ~- G: C" i; u- i
% A5 B4 r, n0 G
! z# N. l: h" A获得参数
- g# T( F7 M7 ~方法一：利用CATIDescendants 接口
/ w: [1 s7 d" J/ W8 ^CATIDescendants_var spDescendantsOnPart = spPrtPart;
/ c2 r& ~' q8 f' ]+ eCATListValCATISpecObject_var spSpecObjects;
piDescendantsOnPart->GetAllChildren("CATICkeParm", spSpecObjects);
+ W! ?/ L& i0 ]3 h+ O方法二：利用CATIParmPublisher 中接口
CATIParmPublisher_var spParmPublisher = spPrtPart;
7 d/ o6 M! F4 h& \. PCATListValCATISpecObject_var ListFound;
spParmPublisher->GetAllChildren("CATICkeParm",ListFound);
方法三：利用CATContainer 中的ListMembersHere 方法
1 O. R: N" Z% h, T' t5 d$ t! lSEQUENCE(CATBaseUnknown_ptr) ListObj;
long NbObj = spContainer ->ListMembersHere("CATICkeParm",ListObj);
for(int j=0;j<NbObj;j++)//注意从0 开始
{
* j/ k! C$ g( X7 i/ T: hCATIAlias_var spAlias = ListObj[j];
! @3 x# [% D6 `! a9 }6 B; Xcout<<spAlias->GetAlias()<<endl; //输出参数的名字
