-    \class QSampleCache
-    \internal
-
-    When you want to get a sound sample data, you need to request the QSample reference from QSampleCache.
-
-    \since 1.1
-
-    \code
-        QSample *m_sample;     // class member.
-
-      private Q_SLOTS:
-        void decoderError();
-        void sampleReady();
-    \endcode
-
-    \code
-      Q_GLOBAL_STATIC(QSampleCache, sampleCache) //declare a singleton manager
-    \endcode
-
-    \code
-        m_sample = sampleCache()->requestSample(url);
-        switch(m_sample->state()) {
-        case QSample::Ready:
-            sampleReady();
-            break;
-        case QSample::Error:
-            decoderError();
-            break;
-        default:
-            connect(m_sample, SIGNAL(error()), this, SLOT(decoderError()));
-            connect(m_sample, SIGNAL(ready()), this, SLOT(sampleReady()));
-            break;
-        }
-    \endcode
-
-    When you no longer need the sound sample data, you need to release it:
-
-    \code
-       if (m_sample) {
-           m_sample->release();
-           m_sample = 0;
-       }
-    \endcode
