我对unique_ptr很陌生。在遇到一个返回新的unique_ptr的函数时遇到了麻烦。编译器似乎抱怨有多个对象可能拥有这个unique_ptr。我不确定如何满足编译器的要求。感谢任何帮助。
void Bar::Boo()
{
...
// m_Goals is of type std::unique_ptr<Goals>
auto x = m_Goals->Foo(); // error: 'std::unique_ptr<_Ty>::unique_ptr' : cannot access private member declared in class 'std::unique_ptr<_Ty>'
//auto x = std::move( m_Goals->Foo() ); // same error
...
}
const std::unique_ptr<Goals> Goals::Foo()
{
std::unique_ptr<Goals> newGoals( new Goals() );
...
return newGoals;
// also tried "return std::move( newGoals )" based on https://dev59.com/92855IYBdhLWcg3wfURM
} // this function compiles
