\class QAbstractUriResolver
\brief The QAbstractUriResolver class is a callback interface for resolving Uniform Resource Identifiers.
\since 4.4
\reentrant
\ingroup xml-tools
A Uniform Resource Identifier (URI) is a string that uniquely
identifies a resource. URIs are versatile global identifiers. It is
often useful to transform a URI that identifies something logical
into a URI that locates something physical (a URL), or to simply map
a URI to a different URI. QAbstractUriResolver::resolve() provides
this functionality.
For example, one could write a QAbstractUriResolver subclass that
rewrites library ISBN number URIs as book title URLs, e.g.,
\e{urn:isbn:0-345-33973-8} would be rewritten as
\e{file:///books/returnOfTheKing.doc}. Or a QAbstractUriResolver
subclass could be written for a web browser to let the web browser
protect the user's private files by mapping incoming requests for
them to null URIs.

\fn QUrl QAbstractUriResolver::resolve(const QUrl &relative, const QUrl &baseURI) const
Returns the \a relative URI resolved using the \a baseURI.
The caller guarantees that both \a relative and \a baseURI are
valid, and that \a baseURI is absolute. \a relative can be relative,
absolute, or empty.
The returned QUrl can be a default constructed QUrl. If it is not a
default constructed QUrl, it will be absolute and valid. If a default
constructed QUrl is returned, it means the \a relative URI was not
accepted to be resolved.
If the reimplemented resolve() function decides it has nothing to do
about resolving the \a relative URI, it should simply return the \a
relative URI resolved against the \a baseURI, i.e.:
\snippet doc/src/snippets/code/src_xmlpatterns_api_qabstracturiresolver.cpp 0
\sa QUrl::isRelative(), QUrl::isValid()
