| [[Syntax] [Code]] |
| [[Pipe] [`rng | boost::adaptors::filtered(pred)`]] |
| [[Function] [`boost::adaptors::filter(rng, pred)`]] |
| ] |
| |
| * [*Precondition:] The `value_type` of the range is convertible to the argument type of `pred`. |
| * [*Postcondition:] For all adjacent elements `[x]` in the returned range, `pred(x)` is `true`. |
| * [*Throws:] Whatever the copy constructor of `pred` might throw. |
| * [*Range Category:] __forward_range__ |
| * [*Range Return Type:] `boost::filtered_range<decltype(rng)>` |
| * [*Returned Range Category:] The minimum of the range category of `rng` and __bidirectional_range__ |
