Hello everyone,
I sometimes saw code with template<> and followed by a class definition, like,
I am wondering the practical usage of this trick. Why declar a template but leaving the content to nothing? If there is no type parameters, I do not think there is a need to put template<> statement.Code:template<> class { // class definition }
thanks in advance,
George
I don't think this is legal. Are you sure it wasn't of the form
?Code:template <> class<a_type> { };
That would be a full specialization.
Edit: Definitely not legal. The production for a template declaration is
This production requires at least one actual parameter.Code:template-declaration: exportopt template < template-parameter-list > declaration template-parameter-list: template-parameter template-parameter-list , template-parameter
