[boost] detect an enum type in template arguments

3 Mar 2011

      Hi,

consider the example below, is there a way to detect an enum type and non-enum type ?

thus if there were a way to do it, assume it to be "is_enum<T>::value" then the output of example below would have been

output:

Generic Type
Enumeration Type

**************************** example begins ***************************

// all types except enumeration come here
template T>
class Foo
{
    void identify()
    {
        std::cout << "Generic";
    }
};

// all enumerations types come here
<template T>
class Foo<is_enum<T>::value>
{
    void identify()
    {
        std::cout << "Enumeration";
    }
};

enum BarEnum { Mon, Tue, Wed };

int main( int argc, char* argv[])
{
    std::cout << Foo<int> << " Type" << std::endl;
    std::cout << Foo<BarEnum> << " Type" << std::endl;
    return 0;
}
