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>
