operator xref:boost/urls/param.adoc[param]();

== Description


This function performs a conversion from
a reference-like query parameter to one
retaining ownership of the strings by
making a copy.
No validation is performed on the strings.

=== Complexity

Linear in `this-&gt;key.size() + this-&gt;value.size()`.

=== Exception Safety

Calls to allocate may throw.
