Hi
In Vertex I want to store field with type like LinkMap but with additional
property.
Something like this:
key="something"
value=@rid+Boolean
So first I thought about Map with custom object as Value type
class Custom {
private ORID rid;
private Boolean read;
//...
}
Map<String, Custom> map;
But first question:
How should I declare field type? (CREATE PROPERTY Vertex.map ???? )
Second:
Above code (when I commit transaction after putting filed with type
Map<String, Custom>) gives me error :
com.orientechnologies.orient.core.exception.OTransactionException: Error on
