Replace params

Synopsis

params_encoded_base::iterator
replace(
    params_encoded_base::iterator pos,
    const param_pct_view& p);

Declared in file <include/boost/url/params_encoded_ref.hpp> on line 705

Defined in file <src/params_encoded_ref.cpp> on line 139

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.

The strings passed in must not come from the element being replaced, or else the behavior is undefined.

Example

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

u.encoded_params().replace( u.encoded_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. Exceptions thrown on invalid input.
