        <h3>Synopsis</h3>
        <div>
            <code>

        <h3>Description</h3>
        <p><span>This function adjusts the path to make</span> <span>it absolute or not, depending on the</span>
<span>parameter.</span></p>

<div>
<h4>NOTE</h4>
<p><span>If an authority is present, the path</span>
<span>is always absolute. In this case, the</span>
<span>function has no effect.</span></p>

</div>
<h3>Example</h3>
<code>
url u( "path/to/file.txt" );
assert( u.set_path_absolute( true ) );
assert( u.buffer() == "/path/to/file.txt" );
</code>
<h3>Postconditions</h3>
<code>
this->is_path_absolute() == true && this->encoded_path().front() == '/'
</code>
<h3>Complexity</h3>
<p><span>Linear in `this->size()`.</span></p>

<h3>BNF</h3>
<code>
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>
