Java-如何在Arangodb上创建边缘？

Question

I created an edge collection using java, but when i try to create a document i get an error on method (insertEdge).

Does anyone know of another method for doing this, or what I might be doing wrong?

BaseEdgeDocument myObject = new BaseEdgeDocument("TurmaA/asd","TurmaA/testepedro");
myObject.addAttribute(nome.getField(), nome.getValue());
collection.insertEdge(myObject, new EdgeCreateOptions());

PS- the error given is a "cannot find symbol (method)"

Answer 1

When reading about cannot find symbol your object ( collection ) which you're trying to invoke the insertEdge method on probably isn't of type edge collection - hence it doesn't have insertEdge-method .

The example code shows how to work with edge collections :

private static EdgeEntity saveEdge(final CircleEdge edge) throws ArangoDBException {
        return db.graph(GRAPH_NAME).edgeCollection(EDGE_COLLECTION_NAME).insertEdge(edge);
}
