Name

Synopsis

9         package URI::jdbc;
10         use parent 'URI::Nested';
11         sub prefix       { 'jdbc' }
12         sub nested_class { undef  }
13         sub subprotocol  { shift->nested_uri->scheme(@_) }
14
15         package main;
16         my $jdbc_uri = URI->new('jdbc:oracle:scott/tiger@//myhost:1521/myservicename');
17         my $nested_uri = $jdbc_uri->nested_uri;

Description

20       This class provides support for nested URIs, where the scheme is a
21       prefix, and the remainder of the URI is another URI. Examples include
22       JDBC URIs
23       <http://docs.oracle.com/cd/B14117_01/java.101/b10979/urls.htm#BEIJFHHB>
24       and database URIs <https://github.com/theory/uri-db>.

Interface

27       The following differences exist compared to the "URI" class interface:
28
29   Class Method
30       "prefix"
31
32       Returns the prefix to be used, which corresponds to the URI's scheme.
33       Defaults to the last part of class name.
34
35       "nested_class"
36
37       Returns the URI subclass to use for the nested URI. If defined, the
38       nested URI will always be coerced into this class if it is not
39       naturally an instance of this class or one of its subclasses.
40
41   Constructors
42       "new"
43
44         my $uri = URI::Nested->new($string);
45         my $uri = URI::Nested->new($string, $base);
46
47       Always returns a URI::Nested object. $base may be another URI object or
48       string. Unlike in URI's "new()", schemes will always be applied to the
49       URI and the nested URI if they does not already schemes. And if
50       "nested_class" is defined, the nested URI will be coerced into that
51       class.
52
53   Accessors
54       "scheme"
55
56         my $scheme = $uri->scheme;
57         $uri->scheme( $new_scheme );
58
59       Gets or sets the scheme part of the URI. When setting the scheme, it
60       must always be the same as the value returned by "prefix" or an
61       exception will be thrown -- although the letter casing may vary. The
62       returned value is always lowercase.
63
64       "nested_uri"
65
66         my $nested_uri = $uri->nested_uri;
67
68       Returns the nested URI.
69
70   Instance Methods
71       "abs"
72
73         my $abs = $uri->abs( $base_uri );
74
75       Returns the URI::Nested object itself. Unlike URI's "abs()",
76       $URI::ABS_ALLOW_RELATIVE_SCHEME is ignored.
77
78       "rel"
79
80         my $rel = $uri->rel( $base_uri );
81
82       Returns the URI::Nested object itself.
