boost::urls::params_ref::set

Synopsis

iterator
set(
    iterator pos,
    core::string_view value);

iterator
set(
    core::string_view key,
    core::string_view value,
    ignore_case_param ic = {});

This function replaces the value of an element at the specified position.

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

url u( "?id=42&id=69" );

u.params().set( u.params().begin(), "none" );

assert( u.encoded_query() == "id=none&id=69" );

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

Strong guarantee. Calls to allocate may throw.

An iterator to the element.

Name Description

Name	Description
pos	An iterator to the element.
value	The value to assign. The empty string still counts as a value. That is, `has_value` for the element is true.
key	The key to match. By default, a case‐sensitive comparison is used.
ic	An optional parameter. If the value ignore_case is passed here, the comparison is case‐insensitive.
