This adaptor produces a range that can be output streamed to a
|
|
`std::basic_ostream` to produce the output string formatted output. With the
|
|
default paramters given numbers 1 to 5 inclusively in a range the output when
|
|
streamed would be "{0,1,2,3,4,5}". The prefix, separator and postfix may be
|
|
passed as parameters.
|
|
|
|
The general format of the output is thus:
|
|
<prefix><element_1><sep><element_2><sep>...<element_n><postfix>
|
|
|
|
* [*Precondition:]
|
|
* `0 <= n`.
|
|
* `sep` has a type that is CopyConstructible and able to be streamed to `std::basic_ostream<Char,Traits>`
|
|
* `prefix` has a type that is CopyConstructible and able to be streamed to `std::basic_ostream<Char,Traits>`
|
|
* `postfix` has a type that is CopyConstructible and able to be streamed to `std::basic_ostream<Char,Traits>`
|
|
* [*Returns:] `boost::range::formatted_range<Iter, Sep, Prefix, Postfix>` where
|
|
`Iter` is `typename boost::range_iterator<Rng>::type`, `Sep` is the separator
|
|
type, `Prefix` is the prefix type and `Postfix` is the postfix type.
|
|
* [*Range Category:] __single_pass_range__
|
|
* [*Returned Range Category:] The range category of `rng`.
