How to get the type of class from a vertex?

[Academia Learning Centro de inglés y de formación]

Hello, I want to empty the db and I was testing this way (I do not know if it's the right one)

Iterable<Vertex> resultIteratorVertices = graph.getVertices(true);

for (Vertex v : resultIteratorVertices){

   graph.command( new OCommandSQL("TRUNCATE CLASS "+ v.getClass + " POLYMORPHIC UNSAFE") ).execute();

}

To remove all records from all classes, but I can not figure out how to get the type of class from each record

EDIT: I think that the best way is:

graph.command( new OCommandSQL("TRUNCATE CLASS V POLYMORPHIC UNSAFE") ).execute();

graph.command( new OCommandSQL("TRUNCATE CLASS E POLYMORPHIC UNSAFE") ).execute();

why you don't just delete and recreate the entire db?

To not delete all classes / schemas / tables only the records

[Ivan Mainetti]

what about something like:

Iterable<Edge> resultIteratorEdges = g.getEdges(true);

for (Edge e : resultIteratorEdges){

e.remove();

}

Iterable<Vertex> resultIteratorVertices = g.getVertices(true);

for (Vertex v : resultIteratorVertices){

v.remove();

}

Mm I do not know, I think truncate is more appropriate, but I do not know ..
