#include <If_Then_Else.h>

Detailed Description

Compile-time selection of type based on a boolean value.

This primary template selects the second or third argument based on the value of the boolean first argument.

Usage example:

template <typename T>
class Foo
{
public:
// Set "TheType" to be the larger of "T" and "int".
typedef typename If_Then_Else<(sizeof (T) > sizeof (int)),
T,
int>::result_type TheType;
};
