My new code snippet is the following:
Map<String, Object> nodeProps = db.getNodeProperties(subjectNode);
if (nodeProps.get(predicateName) != null) {
try { // Property values might be an array
Object[] values = (Object[]) nodeProps.get(predicateName);
ArrayList<Object> valuesList = new ArrayList<>(Arrays.asList(values));
valuesList.add(value);
nodeProps.put(predicateName, valuesList.toArray(new
Object[valuesList.size()]));
} catch (ClassCastException cce) { // or just a value
Object v = nodeProps.get(predicateName);
Object[] valuesList = new Object[]{v, value};
nodeProps.put(predicateName, valuesList.toString());
}
} else {
nodeProps.put(predicateName, value);
}
db.setNodeProperties(subjectNode, nodeProps);
But in the graph I get: synonym [Ljava.lang.Object;@788ab663
I get an exception if I use:
nodeProps.put(predicateName, valuesList.toString());
Which is the right way to put the Object array in nodeProprs.put?
