Detailed Description

Base class for elements of an argument list with mixed types.

This class is typically used as element in an std::initializer_list to build type-safe variable argument lists. Instances of ArgMix are directly built in the initializer list and cannot be copied or assigned.

This is a base class. It can be used only through the two derived classes ArgMixIn and ArgMixOut.
