                                               Object... keyValues)

      Sets a `Property` value and related meta properties if supplied, if supported by the `Graph` and if the `Element` is a `VertexProperty`. This method is the long-hand version of `property(Object, Object, Object...)` with the difference that the `VertexProperty.Cardinality` can be supplied.

      Generally speaking, this method will append an `AddPropertyStep` to the `Traversal` but when possible, this method will attempt to fold key/value pairs into an `AddVertexStep`, `AddEdgeStep` or `AddVertexStartStep`. This potential optimization can only happen if cardinality is not supplied and when meta-properties are not included.
      Parameters:
        `cardinality` - the specified cardinality of the property where `null` will allow the `Graph` to use its default settings
        `key` - the key for the property
        `value` - the value for the property
        `keyValues` - any meta properties to be assigned to this property
      Returns:
        the traversal with the last step modified to add a property

                                               Object... keyValues)

      Sets the key and value of a `Property`. If the `Element` is a `VertexProperty` and the `Graph` supports it, meta properties can be set. Use of this method assumes that the `VertexProperty.Cardinality` is defaulted to `null` which means that the default cardinality for the `Graph` will be used.

      This method is effectively calls `property(org.apache.tinkerpop.gremlin.structure.VertexProperty.Cardinality, Object, Object, Object...)` as `property(null, key, value, keyValues`.
      Parameters:
        `key` - the key for the property
        `value` - the value for the property
        `keyValues` - any meta properties to be assigned to this property
      Returns:
        the traversal with the last step modified to add a property

    - #### index

          default <E2> GraphTraversal<S,E2> index()

      Indexes all items of the current collection. The indexing format can be configured using the `with(String, Object)` and `WithOptions.indexer`. Indexed as list: ["a","b","c"] => [["a",0],["b",1],["c",2]] Indexed as map: ["a","b","c"] => {0:"a",1:"b",2:"c"} If the current object is not a collection, this step will map the object to a single item collection/map: Indexed as list: "a" => ["a",0] Indexed as map: "a" => {0:"a"}
      Returns:
        the traversal with an appended `IndexStep`

    - #### barrier

          default GraphTraversal<S,E> barrier(Consumer<TraverserSet<Object>> barrierConsumer)

      Turns the lazy traversal pipeline into a bulk-synchronous pipeline which basically iterates that traversal to the size of the barrier. In this case, it iterates the entire thing as the default barrier size is set to `Integer.MAX_VALUE`.
      Parameters:
        `barrierConsumer` - a consumer function that is applied to the objects aggregated to the barrier
      Returns:
        the traversal with an appended `NoOpBarrierStep`

    - #### with

          default GraphTraversal<S,E> with(String key)

      Provides a configuration to a step in the form of a key which is the same as `with(key, true)`. The key of the configuration must be step specific and therefore a configuration could be supplied that is not known to be valid until execution.

        `key` - the key of the configuration to apply to a step
      Returns:
