Project: Cayenne
Issue Type: Task
Components: Core Library
Affects Versions: 5.0.M1
Reporter: Ivan Nikitka
The current process for pagination uses direct method for gathering data.
Without any checks, validations and convertations.
{code:java}
public class DataContext extends BaseContext{
...
public ResultIterator performIteratedQuery(Query query)
}{code}
{code:java}
public class IncrementalFaultList<E> implements List<E>, Serializable {
...
protected void fillIn(final Query query, List<Object> elementsList) {
elementsList.clear();
try (ResultIterator<?> it = dataContext.performIteratedQuery(query)) {
while (it.hasNextRow()) {
elementsList.add(it.nextRow());
}
}
unfetchedObjects = elementsList.size();
}{code}
After applying [this|[https://github.com/apache/cayenne/pull/594] ] PR we need
to redirect pagination flow to the
{code:java}
public class DataContext extends BaseContext{
...
public <T> ResultIterator<T> iterator(final Select<T> query)
}{code}
