[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.
