operator=(std::initializer_list<xref:boost/urls/param_view.adoc[param_view]> init);
----

== Description


After assignment, the previous contents        of the query parameters are replaced by        the contents of the initializer‐list.


=== Preconditions

None of character buffers referenced by        `init` may overlap the character buffer of        the underlying url, or else the behavior        is undefined.


=== Effects

[,cpp]
----
this->assign( init );
