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.
