\class QAbstractUriResolver
|
|
50 |
\brief The QAbstractUriResolver class is a callback interface for resolving Uniform Resource Identifiers.
|
|
51 |
\since 4.4
|
|
52 |
\reentrant
|
|
53 |
\ingroup xml-tools
|
|
54 |
|
|
55 |
A Uniform Resource Identifier (URI) is a string that uniquely
|
|
56 |
identifies a resource. URIs are versatile global identifiers. It is
|
|
57 |
often useful to transform a URI that identifies something logical
|
|
58 |
into a URI that locates something physical (a URL), or to simply map
|
|
59 |
a URI to a different URI. QAbstractUriResolver::resolve() provides
|
|
60 |
this functionality.
|
|
61 |
|
|
62 |
For example, one could write a QAbstractUriResolver subclass that
|
|
63 |
rewrites library ISBN number URIs as book title URLs, e.g.,
|
|
64 |
\e{urn:isbn:0-345-33973-8} would be rewritten as
|
|
65 |
\e{file:///books/returnOfTheKing.doc}. Or a QAbstractUriResolver
|
|
66 |
subclass could be written for a web browser to let the web browser
|
|
67 |
protect the user's private files by mapping incoming requests for
|
|
68 |
them to null URIs.

\fn QUrl QAbstractUriResolver::resolve(const QUrl &relative, const QUrl &baseURI) const
|
|
89 |
|
|
90 |
Returns the \a relative URI resolved using the \a baseURI.
|
|
91 |
|
|
92 |
The caller guarantees that both \a relative and \a baseURI are
|
|
93 |
valid, and that \a baseURI is absolute. \a relative can be relative,
|
|
94 |
absolute, or empty.
|
|
95 |
|
|
96 |
The returned QUrl can be a default constructed QUrl. If it is not a
|
|
97 |
default constructed QUrl, it will be absolute and valid. If a default
|
|
98 |
constructed QUrl is returned, it means the \a relative URI was not
|
|
99 |
accepted to be resolved.
|
|
100 |
|
|
101 |
If the reimplemented resolve() function decides it has nothing to do
|
|
102 |
about resolving the \a relative URI, it should simply return the \a
|
|
103 |
relative URI resolved against the \a baseURI, i.e.:
