I have following example (extension to Avoid calling move constructor)
#include <cstdint>
class Interface
{
public:
Interface() = default;
virtual ~Interface() = default;
Interface(const Interface&) = delete;
Interface(Interface&&) = delete;
const Interface& operator=(const Interface&) = delete;
Interface& operator=(Interface&&) = delete;
};
class FooC : public Interface
{
public:
FooC(uint16_t iPort, uint16_t iPin)
: PORT(iPort)
, PIN(iPin)
{
};
FooC() = delete;
~FooC() override = default;
FooC(const FooC&) = delete;
FooC(FooC&&) = delete;
const FooC& operator=(const FooC&) = delete;
FooC& operator=(FooC&&) = delete;
private:
const uint16_t PORT;
const uint16_t PIN;
};
class FactoryC
{
public:
FactoryC()
: mFoo{
{1, 2},
{3, 4}
}
{
};
~FactoryC() = default;
FactoryC(const FactoryC&) = delete;
FactoryC(FactoryC&&) = delete;
const FactoryC& operator=(const FactoryC&) = delete;
FactoryC& operator=(FactoryC&&) = delete;
private:
FooC mFoo[2];
};
int main()
{
FactoryC factory{};
}
and I don't want to call the default, move and copy constructor. Due to that I deleted the functions. Unfortunately this results in following error (compiled with C++17)
<source>: In constructor 'FactoryC::FactoryC()':
<source>:42:4: error: use of deleted function 'FooC::FooC(FooC&&)'
}
^
<source>:26:4: note: declared here
FooC(FooC&&) = delete;
^~~~
Compiler returned: 1
Is it possible to force in this example the calling of constructor with the parameters and still delete the default, move and copy constructor of FooC?
