= Function url_base::set_encoded_path

pass:v,q[Set the path.]


== Synopsis

Declared in header `</boost/url/url_base.hpp#L1796[boost/url/url_base.hpp,window=blank_]>`

[source,cpp,subs="verbatim,macros,-callouts"]
----
xref:boost/urls/url_base.adoc[url_base]&
set_encoded_path(xref:boost/urls/pct_string_view.adoc[pct_string_view] s);
----

== Description

pass:v,q[This function sets the path to the] pass:v,q[string, which may contain percent-escapes]
pass:v,q[and can be empty.]
pass:v,q[Escapes in the string are preserved,]
pass:v,q[and reserved characters in the string]
pass:v,q[are percent-escaped in the result.]
[NOTE]
pass:v,q[The library may adjust the final result]
pass:v,q[to ensure that no other parts of the url]
pass:v,q[is semantically affected.]

=== Example
[,cpp]
----
url u( "http://www.example.com" );

u.set_encoded_path( "path/to/file.txt" );

assert( u.encoded_path() == "/path/to/file.txt" );
----

=== Complexity
pass:v,q[Linear in `this->size() + s.size()`.]

=== Exception Safety
pass:v,q[Strong guarantee.]
pass:v,q[Calls to allocate may throw.]
pass:v,q[Exceptions thrown on invalid input.]

=== BNF
[,cpp]
----
path          = path-abempty    ; begins with "/" or is empty
              / path-absolute   ; begins with "/" but not "//"
              / path-noscheme   ; begins with a non-colon segment
              / path-rootless   ; begins with a segment
              / path-empty      ; zero characters

path-abempty  = *( "/" segment )
path-absolute = "/" [ segment-nz *( "/" segment ) ]
path-noscheme = segment-nz-nc *( "/" segment )
path-rootless = segment-nz *( "/" segment )
path-empty    = 0<pchar>
