Function params_encoded

Replace params

Synopsis

Declared in header </boost/url/params_encoded_ref.hpp#L705[boost/url/params_encoded_ref.hpp,window=blank_]>

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

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.

Note	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.
