Method Details

asAdmin

public GraphTraversal.Admin<S,E> asAdmin()

Description copied from interface: Traversal

Get access to administrative methods of the traversal via its accompanying Traversal.Admin.

Specified by:

asAdmin in interface GraphTraversal<S,E>

Specified by:

asAdmin in interface Traversal<S,E>

Overrides:

asAdmin in class DefaultTraversal<S,E>

Returns:

the admin of this traversal

iterate

public GraphTraversal<S,E> iterate()

Description copied from interface: Traversal

Iterate all the Traverser instances in the traversal. What is returned is the empty traversal. It is assumed that what is desired from the computation is are the sideEffects yielded by the traversal.

Specified by:

iterate in interface GraphTraversal<S,E>

Specified by:

iterate in interface GraphTraversal.Admin<S,E>

Specified by:

iterate in interface Traversal<S,E>

Returns:

the fully drained traversal

clone

public DefaultGraphTraversal<S,E> clone()

Description copied from interface: Traversal.Admin

Cloning is used to duplicate the traversal typically in OLAP environments.

Specified by:

clone in interface GraphTraversal.Admin<S,E>

Specified by:

clone in interface Traversal.Admin<S,E>

Overrides:

clone in class DefaultTraversal<S,E>

Returns:

The cloned traversal
