Detailed Description

template<typename T>
class UT_VariadicT< T >

Build a list of variadic arguments of the given template type

C-Style variadic arguments are error prone for various reasons:

• No type checking
• NULL termination issues

This class provides type-safety and a cleaner interface. For example, to accept a variable length array of strings:

typedef UT_VariadicT<const char *>      VariadicStrings;
void
function(const VariadicStrings &strings)
{
    for (exint i = 0; i < strings.entries(); ++i)
        cerr << i << " " << strings.item(i) << " " strlen(strings.item(i));
}

// Which can be called using
function(VariadicStrings() << "hello" << "world");
