Thread: Templated operator overload WITH a specific parameter type

I'm having trouble doing some overloads.
It's trying to run this on every instance of the << or >> operators... I ONLY want it to do that if they contain the type any, explicitly... I don't want it to run the constructor!

Be prepared for a lot of code:

Code:

template <any, typename UnknownType>
	any operator <<(const any & lhs, const UnknownType & rhs)
	{
		any result;

		if (lhs.type() == typeid(UnknownType))	// check that types are same.
												// don't use float or double!
			result = any_cast<UnknownType>(lhs) << rhs;

		return result;   // returns a copy of result
	}

Code:

	template <typename UnknownType>
	UnknownType operator <<(const UnknownType & lhs, const any & rhs)
	{
		UnknownType result;

		if (rhs.type() == typeid(UnknownType))	// check that types are same.
												// don't use float or double!
			result = lhs << any_cast<UnknownType>(rhs);

		return result;   // returns a copy of result
	}

Code:

	template <any, typename UnknownType>
	any operator >>(const any & lhs, const UnknownType & rhs)
	{
		any result;

		if (lhs.type() == typeid(UnknownType))	// check that types are same.
												// don't use float or double!
			result = any_cast<UnknownType>(lhs) >> rhs;

		return result;   // returns a copy of result
	}

Code:

	template <typename UnknownType>
	UnknownType operator >>(const UnknownType & lhs, const any & rhs)
	{
		UnknownType result;

		if (rhs.type() == typeid(UnknownType))	// check that types are same.
												// don't use float or double!
			result = lhs >> any_cast<UnknownType>(rhs);

		return result;   // returns a copy of result
	}

Its having trouble figuring out which overloads to do.
I believe this is because it tries to do the one with UnknownType as parameter 1 instead of the ostream/istream...

What am I doing wrong?
