Prototype

template<class ForwardRange, class Generator>
ForwardRange& generate( ForwardRange& rng, Generator gen );

template<class ForwardRange, class Generator>
const ForwardRange& generate( const ForwardRange& rng, Generator gen );

Description

generate assigns the result of gen() to each element in range rng. Returns the resultant range.

Definition

Defined in the header file boost/range/algorithm/generate.hpp

Requirements
  • ForwardRange is a model of the Forward Range Concept.
  • ForwardRange is mutable.
  • Generator is a model of the GeneratorConcept.
  • The value_type of SinglePassRange is convertible to a type in OutputIterator's set of value types.
Precondition:
  • out_it is not an iterator within rng.
  • [out_it, out_it + distance(rng)) is a valid range.
Complexity

Linear. Exactly distance(rng) assignments are performed.
