Hi,
With the code snippet:
private static void test() {
OPartitionedDatabasePool databasePool =
new OPartitionedDatabasePool("memory:sandbox", "admin", "admin");
/* create 3 Person docs */
try (ODatabaseDocumentTx db = databasePool.acquire()) {
db.begin();
ODocument luke = new ODocument("Person")
.field("name", "Luke").field("friends", new HashSet<ODocument
>());
ODocument friend1 = new ODocument("Person")
.field("name", "friend1").field("friends", new HashSet<ODocument
>());
ODocument friend2 = new ODocument("Person")
.field("name", "friend2").field("friends", new HashSet<ODocument
>());
luke.save();
friend1.save();
friend2.save();
db.commit();
}
/* add 2 friends to Luke */
try (ODatabaseDocumentTx db = databasePool.acquire()) {
db.begin();
OSQLSynchQuery<ODocument> query = new OSQLSynchQuery<ODocument>(
"select from Person where name = ?");
ODocument luke = ((List<ODocument>) db.command(query).execute("Luke"
)).get(0);
ODocument friend1 = ((List<ODocument>) db.command(query).execute(
"friend1")).get(0);
ODocument friend2 = ((List<ODocument>) db.command(query).execute(
"friend2")).get(0);
Set<ODocument> friendsLink = luke.field("friends", OType.LINKSET);
friendsLink.add(friend1);
friendsLink.add(friend2);
luke.save();
db.commit();
}
/* check type of objects returns in the "friends" mv link */
try (ODatabaseDocumentTx db = databasePool.acquire()) {
OSQLSynchQuery<ODocument> query = new OSQLSynchQuery<ODocument>(
"select from Person where name = ?");
ODocument luke = ((List<ODocument>) db.command(query).execute("Luke"
)).get(0);
Object friends = luke.field("friends", OType.LINKSET);
for (Object friend : (Collection<?>)friends) {
System.out.println(" " + friend.getClass().getSimpleName());
<--- prints "ORecordId" in 2.0 RC1, prints ODocument in 1.7.9
}
}
}
In 1.7.9, multi-valued link field returns a collection of
ODocument(expected), but in 2.0 RC1 it returns a collection of ORecordId.
Is this a bug in 2.0 RC1 or am I missing something?
I am using memory storage.
Thanks!
fei
