                    Object... keyValues)
        Description copied from interface: Vertex
        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 String property keys and the even numbered arguments are the related property values.
        Specified by:
        addEdge in interface Vertex
        Parameters:
        label - The label of the edge
        inVertex - The vertex to receive an incoming edge from the current vertex
        keyValues - The key/value pairs to turn into edge properties
        Returns:
        the newly created edge

      • property

        public <V> VertexProperty<V> property​(String key,
                                      V value,
                                      Object... keyValues)
        Description copied from interface: Vertex
        Set the provided key to the provided value using default VertexProperty.Cardinality for that key. The default cardinality can be vendor defined and is usually tied to the graph schema. The default implementation of this method determines the cardinality graph().features().vertex().getCardinality(key). The provided key/values are the properties of the newly created VertexProperty. These key/values must be provided in an even number where the odd numbered arguments are String.
        Specified by:
        property in interface Vertex
        Type Parameters:
        V - the type of the value of the vertex property
        Parameters:
        key - the key of the vertex property
        value - The value of the vertex property
        keyValues - the key/value pairs to turn into vertex property properties
        Returns:
        the newly created vertex property

      • property

        public <V> VertexProperty<V> property​(VertexProperty.Cardinality cardinality,
                                      String key,
                                      V value,
                                      Object... keyValues)
        Description copied from interface: Vertex
        Create a new vertex property. If the cardinality is VertexProperty.Cardinality.single, then set the key to the value. If the cardinality is VertexProperty.Cardinality.list, then add a new value to the key. If the cardinality is VertexProperty.Cardinality.set, then only add a new value if that value doesn't already exist for the key. If the value already exists for the key, add the provided key value vertex property properties to it.
        Specified by:
        property in interface Vertex
        Type Parameters:
        V - the type of the value of the vertex property
        Parameters:
        cardinality - the desired cardinality of the property key
        key - the key of the vertex property
        value - The value of the vertex property
        keyValues - the key/value pairs to turn into vertex property properties
        Returns:
        the newly created vertex property
