Hi,
Can someone please help with getting/querying index by key. I m using
1.7rc2SS.
I created a notunique index on vertex with string property from console.
Create index idxtest2 on myclass(ID) notunique
OrientGraphFactory factory = new OrientGraphFactory("remote:local/test2",
"root","password").setupPool(1, 10);
OrientGraph graph = factory.getTx();
Index idx =
graph.getRawGraph().getMetadata().getIndexManager().getIndex("idxtest2");
ORID key = idx.get("indexKey");
or
Index<Vertex> index = graph.getIndex("idxtest2", Vertex.class);
Iterable<Vertex> results = index.get("ID","06615119"); OR Iterable<Vertex>
results = index.get("key","06615119");
Errors on these scenarios are like
ORID key = idx.get("indexKey");
^
required: String,Object
found: String
reason: actual and formal argument lists differ in length
where T is a type-variable:
T extends Element declared in interface Index
2 errors
Exception in thread "main" java.lang.NullPointerException
