Heck, I'll just share the query method:
private SchoolPeopleData[] queryPeoples(SchoolPeopleDataFilter filter) {
String qfilter = null;
// filter a batch of ids
List<Key> keysList = null;
if (filter.getUseIds() == true) {
keysList = getFilterForIds(filter);
if (keysList != null) {
qfilter = ":keys.contains(key)";
}
if (keysList == null || keysList.size() == 0) {
return null;
}
}
ArrayList<SchoolPeopleData> a = new ArrayList<SchoolPeopleData>();
PersistenceManager pm = sp.getPersistenceManager();
try {
Query q = pm.newQuery("select from " + SchoolPeopleJdo.class.getName());
if (qfilter != null) {
q.setFilter(qfilter);
}
q.setRange(filter.getRangeStart(), filter.getRangeFinish());
List<SchoolPeopleJdo> ids = null;
if (filter.getUseIds() == true && keysList != null) {
ids = (List<SchoolPeopleJdo>) q.execute(keysList);
} else {
ids = (List<SchoolPeopleJdo>) q.execute();
}
Iterator<SchoolPeopleJdo> itr = ids.iterator();
while (itr.hasNext()) {
SchoolPeopleJdo j = itr.next();
if (j != null) {
SchoolPeopleJdo detatched = pm.detachCopy(j);
a.add(detatched.getData());
}
}
q.closeAll();
} catch (Exception e) {
e.printStackTrace();
log.log(Level.SEVERE, "", e);
} finally {
pm.close();
}
if (a.size() == 0) {
return null;
}
SchoolPeopleData[] r = new SchoolPeopleData[a.size()];
a.toArray(r);
return r;
}
