View Template Library

mutable_view_tag

Description

mutable_view_tag is an empty class: it has no member functions, member variables, or nested types. It is used solely as a "tag": a concept within the C++ type system. Specifically, it is used as argument to a view template to determin whether the container is to be modifible by the view or not. Its existence allows us to specialize the view_traits<> class to generate the appropriate typedefs for the view iterators and view domain types.

Example

filter_view< vector, bool(*)(int const &),mutable_view_tag> x;
