/**
|
|
33 |
* A class to represent a Uniform Resource Identifier (URI). This class
|
|
34 |
* is designed to handle the parsing of URIs and provide access to
|
|
35 |
* the various components (scheme, host, port, userinfo, path, query
|
|
36 |
* string and fragment) that may constitute a URI.
|
|
37 |
* <p>
|
|
38 |
* Parsing of a URI specification is done according to the URI
|
|
39 |
* syntax described in RFC 2396
|
|
40 |
* <http://www.ietf.org/rfc/rfc2396.txt?number=2396>. Every URI consists
|
|
41 |
* of a scheme, followed by a colon (':'), followed by a scheme-specific
|
|
42 |
* part. For URIs that follow the "generic URI" syntax, the scheme-
|
|
43 |
* specific part begins with two slashes ("//") and may be followed
|
|
44 |
* by an authority segment (comprised of user information, host, and
|
|
45 |
* port), path segment, query segment and fragment. Note that RFC 2396
|
|
46 |
* no longer specifies the use of the parameters segment and excludes
|
|
47 |
* the "user:password" syntax as part of the authority segment. If
|
|
48 |
* "user:password" appears in a URI, the entire user/password string
|
|
49 |
* is stored as userinfo.
|
|
50 |
* <p>
|
|
51 |
* For URIs that do not follow the "generic URI" syntax (e.g. mailto),
|
|
52 |
* the entire scheme-specific part is treated as the "path" portion
|
|
53 |
* of the URI.
|
|
54 |
* <p>
|
|
55 |
* Note that, unlike the java.net.URL class, this class does not provide
|
|
56 |
* any built-in network access functionality nor does it provide any
|
|
57 |
* scheme-specific functionality (for example, it does not know a
|
|
58 |
* default port for a specific scheme). Rather, it only knows the
|
|
59 |
* grammar and basic set of operations that can be applied to a URI.
