Detailed Description

template<typename It>
class vcl::View< It >

The View class is a simple class that stores and exposes two iterators begin and end.

It is useful for classes that expose multiple containers, and they do not expose the classic member functions begin()/end(). In these cases, it is possible to expose the view of a selected container by returning a View object initialized with the begin/end iterators.

For example, a Mesh can expose Vertex and Face containers. The mesh exposes the member functions:

• vertexBegin()
• vertexEnd()
• faceBegin()
• faceEnd() To allow view iteration over vertices, the Mesh could expose a vertices() member function that returns a View object that is constructed in this way:

auto vertices() { return View{vertexBegin(), vertexEnd()}; }
