template<class ForwardRange, class UnaryPredicate, class Value> ForwardRange& replace_if(ForwardRange& rng, UnaryPredicate pred, const Value& with_what); template<class ForwardRange, class UnaryPredicate, class Value> const ForwardRange& replace_if(const ForwardRange& rng, UnaryPredicate pred, const Value& with_what);
replace_if replaces every
element x in rng for which pred(x) == true with with_what.
Returns a reference to rng.
Defined in the header file boost/range/algorithm/replace_if.hpp
ForwardRange is a
model of the Forward
Range Concept.
ForwardRange is mutable.
UnaryPredicate is
a model of the PredicateConcept
ForwardRange's value
type is convertible to UnaryPredicate's
argument type.
Value is convertible
to ForwardRange's
value type.
Value is a model
of the AssignableConcept.
Linear. replace_if performs
exactly distance(rng)
applications of pred,
and at most distance(rng) assignments.
