Replace params

Synopsis

Declared in header <boost/url/params_encoded_ref.hpp>

template<class FwdIt>
iterator
replace(
    iterator from,
    iterator to,
    FwdIt first,
    FwdIt last);

Description

This function replaces a range of params with a range of params.

All iterators that are equal to from or come after are invalidated.

Note
 The strings referenced by the inputs must not come from the underlying url, or else the behavior is undefined.

Mandates

std::is_convertible< std::iterator_traits< FwdIt >::reference_type, param_pct_view >::value == true

Complexity

Linear in this->url().encoded_query().size().

Exception Safety

Strong guarantee. Calls to allocate may throw. Exceptions thrown on invalid input.

Exceptions
