示例1:
/**
* Test accessing a JSONArray's members
*/
bool
example_1(Zorba* aZorba)
{
Iterator_t lIterator;
XQuery_t lQuery = aZorba->compileQuery("[ 1, 2, 3 ]");
lIterator = lQuery->iterator();
lIterator->open();
Item lItem;
lIterator->next(lItem);
// Ensure we got a JSON array
if (!lItem.isJSONItem() ||
lItem.getJSONItemKind() != store::StoreConsts::jsonArray) {
std::cerr << "Item is not JSON Array!" << std::endl;
return false;
}
// Ensure array has 3 integer members
uint64_t lSize = lItem.getArraySize();
if (lSize != 3) {
std::cerr << lSize << " array members returned, expecting 3" << std::endl;
return false;
}
for(uint64_t i = 1; i <= lSize; ++i)
{
Item lMember = lItem.getArrayValue(i);
// This will throw an exception if the item isn't an integer
std::cout << lMember.getLongValue() << std::endl;
}
lIterator->close();
return true;
}示例2: lSequence
// test for bug #3085093 "ZorbaError not caught in SerializerImpl::serialize"
bool
test_serialization_error(Zorba* aZorba)
{
XQuery_t lQuery = aZorba->compileQuery("<a a='1'/>/@a");
Zorba_SerializerOptions_t lOptions;
Serializer_t lSerializer = Serializer::createSerializer(lOptions);
Iterator_t lIterator = lQuery->iterator();
try {
lIterator->open();
Item lItem;
while ( lIterator->next(lItem) ) {
// we have to wrap the item in a Serializable object
SingletonItemSequence lSequence(lItem);
lSerializer->serialize(&lSequence, std::cout);
}
lIterator->close();
} catch (ZorbaException& e) {
std::cerr << e << std::endl;
lIterator->close();
return true;
}
return false;
