求助：大虾，解释一下，关于指针的。

[九羽]

m_pView->getOperatorManager()->setCurrentOperator(m_operator);这样一句话，看不懂啊！！


bool DPntCldRegistration::createOperator()
{
// create an operator for polyline design
m_operator = new RE_OpPntCldRegistration(m_pView);

// set the operator into operator manager

m_pView->getOperatorManager()->setCurrentOperator(m_operator);//这种变量指向函数再指向函数怎么能让在下懂一点。纠结

enablePointCloudSelection();
enableLocalFeatureSelection();
CMainFrame *pWnd;
pWnd = (CMainFrame *) (AfxGetApp()->m_pMainWnd);
pWnd->WriteOperationPrompt(IDS_PNT_CLD_REGISTRATION);

return true;
}
-----------------------------------------------------------------------------------------------------------
RE_OperatorsManager* getOperatorManager()
{ return m_pOpManager; }
-----------------------------------------------------------------------------------------------------------

void RE_OperatorsManager::setCurrentOperator(
RE_BaseOperator *_NewOperator)
{
updateOpHistory();
m_pOperator = _NewOperator;
}

求哪位大哥解释一下。严重感谢。。。。

[真相重于对错]

那个函数返回一个类指针

[退学者的游戏]

比如
X* getOperatorManager();
架设你的getOperatorManager()返回类型为X*。

m_pView->getOperatorManager() //返回了一个X*类型的指针
->setCurrentOperator(m_operator);//调用了X::setCurrentOperator(m_operator);
