  \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.:
