Synopsis

params_base::iterator
replace(
    params_base::iterator pos,
    const param_view& p);

Declared in file <include/boost/url/params_ref.hpp> on line 691

Defined in file <src/params_ref.cpp> on line 124

Description

This function replaces the contents of the element at pos with the specified param. All iterators that are equal to pos or come after are invalidated.

Example

url u( "?first=John&last=Doe" );

u.params().replace( u.params().begin(), { "title", "Mr" });

assert( u.encoded_query() == "title=Mr&last=Doe" );

Complexity

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

Exception Safety

Strong guarantee. Calls to allocate may throw.
