E2411 Declaration of member function default parameters after a specialization has already been expanded (C++)
Go Up to Compiler Errors And Warnings (C++) Index
If a member function of a class template is declared, and then a specialization of that class implicitly instantiated, and later that member function defined with default parameters specified, the above error will result. For example:
template<int i> class foo { void method(int a, int b = i); }; foo<10> x; template<int i> void foo<i>::method(int a = i, int b); // error!
