Question

I have something resembling the following setup:

namespace MyNamespace
{
    enum MyEnum{
        Type1,
        Type2
    };

    class MyClass
    {
        private:
            void MyFunction( MyEnum::Type1 );
    };
}

I would have assumed that since both MyEnum and MyClass are within MyNAmespace, using the enumerated types within the class wouldn’t be a problem, but when I try to compile it I get the following error:

'MyEnum::Type1' is not a type

How can I fix this so I can use my enum and class in the same namespace?

MyEnum is how you would reference it.

namespace MyNamespace
{
    enum MyEnum{
        Type1,
        Type2
    };

    class MyClass
    {
        private:
            void MyFunction( MyEnum );
    };
}

where the definition might look like this:

namespace MyNamespace
{
  void MyClass::MyFunction( MyEnum val) {
    if (val == Type1)
      std::cout << "Type1" << std::endl;
  }
}
