window provides a sliding window over a sequence. It behaves as an iterator which value type is a container for the window's elements. Slide the window using its operator++() . An operator[]() is provided for convenience.
InputIterator | The sequence's input iterator type. | |
WSize | The window's size (length). | |
Step | Number of elements to "eat" when calling increment(). | |
Bottom | Exact type or bottom (see static_base). |
