Detailed Description
Uri represents a single URI.
It is a very thin wrapper around a string. Its purpose is to allow us to distinguish between abbreviated URIs (CURIEs) which may be subject to prefix expansion (represented by strings) and full URIs (represented by Uri).
In terms of the Turtle syntax, anything written within angle brackets is a Uri, while a bare string in URI context is not: it should be stored as a QString and converted to a Uri using Store::expand(). For example, <http://xmlns.com/foaf/0.1/name> is a Uri, while foaf:name is just a string. Never store the latter form in a Uri object without expanding it first.
(Wherever a method in Dataquay accepts a URI as a QString type, it is safe to assume that it will expand any prefixes used in the URI before use. Some methods may exist in alternative forms with Uri or QString arguments; in this case the QString form does prefix expansion, while the Uri form does not.)
Dataquay uses Uri in preference to QUrl because the latter is relatively slow to convert to and from string forms. Uri imposes no overhead over a string, it simply aids type safety.

Constructor & Destructor Documentation
| Dataquay::Uri::Uri | ( | ) | [inline] |
| Dataquay::Uri::Uri | ( | const QString & | s | ) | [inline, explicit] |
Construct a URI from the given string, which is expected to contain the text of a complete well-formed URI.
To construct a Uri from an abbreviated URI via prefix expansion, use Store::expand() instead. This constructor is intentionally marked explicit; no silent conversion is available.
