uri-p

Arguments: object

This predicate function returns true if object is an instance of class uri.

Because the iri class (the class of Internationalized Resource Identifiers or IRIs) is a subclass of the uri class, this function will return true when applied to an iri object. However, although every URI is an IRI, not every IRI is a URI so this function cannot be used to identify objects as strict URIs. A function which would do so would be like:

(defun strict-uri-p (object)
   (and (uri-p object) (null (iri-p object))))

See also the class iri and iri-p.

See also uri.htm for general information on Universal Resource Indicator support in Allegro CL.
