Detailed Description
template<typename F, typename Size = values::unbounded_size_t>
struct OpenKalman::collections::generate_view< F, Size >
A collection_view created by lazily generating elements based on an index.
Typically, the generating function will be a closure.
- Template Parameters
-
F A callable object (possibly a closure) taking an index and producing an output value corresponding to the index. This should preferably be able to take a values::fixed index argument. Size The size of the output collection. If it is values::unbounded_size_t, the view is unsized.
Member Function Documentation
◆ begin() [1/2]
template<typename F, typename Size = values::unbounded_size_t>
|

- Returns
- An iterator at the beginning, if the base object is a range.
◆ begin() [2/2]
template<typename F, typename Size = values::unbounded_size_t>
|
inline |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
◆ end() [1/2]
template<typename F, typename Size = values::unbounded_size_t>

- Returns
- An iterator at the end, if the base object is a range.
