Dynamic Method Handling

- -

- This class handles dynamic methods through the method_missing method - -

- -
-
-
- - public - URIRef - method_missing(methodname, *args) - - -
- -
-

-Allows the construction of arbitrary URIs on the namespace. -

-

Example

-
-  foaf = Namespace.new("http://xmlns.com/foaf/0.1/", "foaf"); foaf.knows # => returns a new URIRef with URI "http://xmlns.com/foaf/0.1/knows"
-  foaf = Namespace.new("http://xmlns.com/foaf/0.1/", "foaf", true); foaf.knows # => returns a new URIRef with URI "http://xmlns.com/foaf/0.1/#knows"

Parameters:

-
- -
- - [String] - - - uri - -
-
-

-the URI of the namespace -

- -
- -
- - [String] - - - short - -
-
-

- - [Boolean] - - - fragment - -
-
-

-are the identifiers on this resource fragment identifiers? (e.g. -’#’) Defaults to false. -

- -
- -
-
-
-

Returns:

-
- -
