URI::Nested(3) Nested URIs

Synopsis

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

Description

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

Interface

The following differences exist compared to the "URI" class interface:

Class Method

"prefix"

Returns the prefix to be used, which corresponds to the URI's scheme. Defaults to the last part of class name.

"nested_class"

Returns the URI subclass to use for the nested URI. If defined, the nested URI will always be coerced into this class if it is not naturally an instance of this class or one of its subclasses.

Constructors

"new" 

  my $uri = URI::Nested->new($string);
  my $uri = URI::Nested->new($string, $base);

Always returns a URI::Nested object. $base may be another URI object or string. Unlike in URI's "new()", schemes will always be applied to the URI and the nested URI if they does not already schemes. And if "nested_class" is defined, the nested URI will be coerced into that class.

Accessors

"scheme" 

  my $scheme = $uri->scheme;
  $uri->scheme( $new_scheme );

Gets or sets the scheme part of the URI. When setting the scheme, it must always be the same as the value returned by "prefix" or an exception will be thrown --- although the letter casing may vary. The returned value is always lowercase.

"nested_uri" 

  my $nested_uri = $uri->nested_uri;

Returns the nested URI.

Instance Methods

"abs" 

  my $abs = $uri->abs( $base_uri );

Returns the URI::Nested object itself. Unlike URI's "abs()", $URI::ABS_ALLOW_RELATIVE_SCHEME is ignored.

"rel" 

  my $rel = $uri->rel( $base_uri );

Returns the URI::Nested object itself.
