2005-04-20 Andrew John Hughes <gnu_andrew@member.fsf.org>
* java/net/URI.java:
Added class documentation.
(parseURI(String)): Only handle scheme-specific parts
if URI is not opaque. Allow for parts that can't be null.
(toString()): Output the scheme-specific part whole, rather
than as its possibly non-existent components.
2005-04-20 Jeroen Frijters <jeroen@frijters.net>
* java/net/URI.java (AUTHORITY_REGEXP): Corrected regexp.
(AUTHORITY_USERINFO_GROUP,AUTHORITY_HOST_GROUP,AUTHORITY_PORT_GROUP):
Adjusted to match new regexp.
