The nsIURI class is an interface to the URI behaviour for parsing
|
|
portions out of a URI. This follows Tim Berners-Lee's URI spec at-
|
|
|
|
http://www.w3.org/Addressing/URI/URI_Overview.html
|
|
|
|
For the purpose of this class, here is the most elaborate form of a URI
|
|
and its corresponding parts-
|
|
|
|
ftp://username:password@hostname:portnumber/pathname
|
|
\ / \ / \ / \ /\ /
|
|
- --------------- ------ -------- -------
|
|
| | | | |
|
|
| | | | Path
|
|
| | | Port
|
|
| | Host
|
|
| PreHost
|
|
Scheme
|
|
|
|
Note that this class does not assume knowledge of search/query portions
|
|
embedded within the path portion of the URI.
|
|
|
|
This class pretty much "final" and there shouldn't be anything added.
|
|
If you do feel something belongs here, please do send me a mail. Thanks!
