示例1: evaluate
void tst_QXmlResultItems::evaluate() const
{
QFETCH(QString, queryString);
QXmlQuery query;
query.setQuery(queryString);
QVERIFY(query.isValid());
QXmlResultItems result;
query.evaluateTo(&result);
QXmlItem item(result.next());
while(!item.isNull())
{
QVERIFY(!result.current().isNull());
QVERIFY(!result.hasError());
item = result.next();
}
/* Now, stress beyond the end. */
for(int i = 0; i < 3; ++i)
{
QVERIFY(result.current().isNull());
QVERIFY(result.next().isNull());
}
}示例2: current
void tst_QXmlResultItems::current() const
{
/* Check default value. */
{
QXmlResultItems result;
QVERIFY(result.current().isNull());
}
/* Stress it on a default constructed value. */
{
QXmlResultItems result;
QVERIFY(result.current().isNull());
QVERIFY(result.current().isNull());
QVERIFY(result.current().isNull());
}
}示例3: constCorrectness
void tst_QXmlResultItems::constCorrectness() const
{
const QXmlResultItems result;
/* These functions should be const. */
result.current();
result.hasError();
}示例4: evalateWithInstantError
/*!
What's special about this is that it's not the QAbstractXmlForwardIterator::next()
that triggers the error, it's QPatternist::Expression::evaluateSingleton() directly.
*/
void tst_QXmlResultItems::evalateWithInstantError() const
{
QXmlQuery query;
MessageSilencer silencer;
query.setMessageHandler(&silencer);
query.setQuery(QLatin1String("fn:error()"));
QXmlResultItems result;
query.evaluateTo(&result);
/* Check the values, and stress it. */
for(int i = 0; i < 3; ++i)
{
QVERIFY(result.current().isNull());
QVERIFY(result.next().isNull());
QVERIFY(result.hasError());
}
