BloombergLP::bsltf::ArgumentType

Declared in <bsltf_argumenttype.h>

This class template wraps an integer value and provides implicit conversion to, and explicit conversion from, int, while keeping track of copy and move operations. Its main purpose is for following an argument through a forwarding interface in test drivers. Each value of the template parameter N yields a unique type, enabling a test driver to distingusih them when calling through a function template interface, thereby avoiding ambiguities or accidental switching of arguments in the implementation of test‐class methods and constructors or in calls to methods and constructors of a class template under test. When an object of this type is copied or moved (via construction or assignment), the value returned by the copyMoveState accessor (the copy/move state), is updated for the target object and, in the case of a move, for the source object as well.
