          public <V> VertexProperty<V> property(String key)

      Description copied from interface: `Vertex`
      Get the `VertexProperty` for the provided key. If the property does not exist, return `VertexProperty.empty()`. If there are more than one vertex properties for the provided key, then throw `Vertex.Exceptions.multiplePropertiesExistForProvidedKey(java.lang.String)`.
      Specified by:
        `property` in interface `Element`
      Specified by:
        `property` in interface `Vertex`
      Type Parameters:
        `V` - the expected type of the vertex property value
      Parameters:
        `key` - the key of the vertex property to get
      Returns:
        the retrieved 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

    - #### keys
