| [heading Description] |
| |
| `irange` is a function to generate an Integer Range. |
| |
| `irange` allows treating integers as a model of the __random_access_range__ Concept. It should be noted that the `first` and `last` parameters denoted a half-open range. |
| |
| [heading Definition] |
| |
| Defined in the header file `boost/range/irange.hpp` |
| |
| [heading Requirements] |
| |
| # `Integer` is a model of the `Integer` Concept. |
| # `StepSize` is a model of the `SignedInteger` Concept. |
| |
| [heading Complexity] |
| |
| Constant. Since this function generates a new range the most significant performance cost is incurred through the iteration of the generated range. |
