Examples of com.tinkerpop.gremlin.structure.Vertex.addEdge()

com.tinkerpop.gremlin.structure.Vertex.addEdge()
Add an outgoing edge to the vertex with provided label and edge properties as key/value pairs. These key/values must be provided in an even number where the odd numbered arguments are {@link String}property keys and the even numbered arguments are the related property values. Hidden properties can be set by specifying the key as {@link com.tinkerpop.gremlin.structure.Graph.Key#hide}. @param label The label of the edge @param inVertex The vertex to receive an incoming edge from the current vertex @param keyValues The key/value pairs to turn into edge properties @return the newly created edge
