static_url::set_path_absolute

(Inherited from url_base)

Set if the path is absolute.

Synopsis
bool
set_path_absolute(
    bool absolute);
Description

This function adjusts the path to make it absolute or not, depending on the parameter.

Remarks

If an authority is present, the path is always absolute. In this case, the function has no effect.

Example
url u( "path/to/file.txt" );
assert( u.set_path_absolute( true ) );
assert( u.buffer() == "/path/to/file.txt" );
Postconditions
this->is_path_absolute() == true && this->encoded_path().front() == '/'
Return Value

true on success.

Complexity

Linear in this->size().

BNF
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>
