See RFC 2396 for a
description of URI references and related terms.
For parsing absolute URI references, this service tries to use a
scheme-specific parser. Such a scheme-specific parser will typically enforce
additional restrictions during parsing, and will typically return objects
that support extra, scheme-specific interfaces in addition to
XUriReference . If no such parser
is found, and for relative URI references, a generic parser is used, which
returns objects that only support
XUriReference .
Locating a scheme-specific parser works as follows: A scheme consists of
Latin captial letters
“ A ”–“ Z ”, Latin small
letters “ a ”–“ z ”,
digits “ 0 ”–“ 9 ”,
“ + ”, “ - ”, and
“ . ”. A scheme s is transformed into
a string s ′ character-by-character, by translating
Lating capital letters to their small counterparts, translating
“ + ” to “ PLUS ”,
“ - ” to “ HYPHEN ”,
“ . ” to “ DOT ”, and copying
Latin small letters and digits unchanged. If the component context used
while creating this UriReferenceFactory instance offers a
service manager, and there is a service available at that service manager
whose name is the concatenation of
“ com.sun.star.uri.UriSchemeParser_ ” and
s ′, then that service is used. It is an error if that
service does not support
XUriSchemeParser .
