Hi,
You can create a List<ODocument> and store it as a property value, eg.
OrientVertex v = ...
List<ODocument> values = new ArrayList<ODocument>();
for(...){
ODocument item = new ODocument("Bid");
item.field("bid", 5.01);
item.field("buyer", buyer);
values.add(item);
}
v.setProperty("bids", values);
Just make sure that the schema is correctly defined, ie. that the "bids"
property is defined as an embeddedlist, otherwise it will be saved as a
link list
Thanks
Luigi
