output_iterator_tag

Category: iterators

Component type: type

Output_iterator_tag is an empty class: it has no member functions, member variables, or nested types. It is used solely as a "tag": a representation of the Output Iterator concept within the C++ type system. Specifically, it is used as a return value for the function iterator_category. Iterator_category takes a single argument, an iterator, and returns an object whose type depends on the iterator's category. Iterator_category's return value is of type output_iterator_tag if its argument is an Output Iterator.
