Method Detail

addStep

default <E2> GraphTraversal.Admin<S,E2> addStep(Step<?,E2> step)

Description copied from interface: Traversal.Admin

Add a Step to the end of the traversal. This method should link the step to its next and previous step accordingly.

Specified by:

addStep in interface Traversal.Admin<S,E>

Type Parameters:

E2 - the output of the step

Parameters:

step - the step to add

Returns:

the updated traversal

iterate

default 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 Traversal<S,E>

Returns:

the fully drained traversal

clone

GraphTraversal.Admin<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 Traversal.Admin<S,E>

Returns:

The cloned traversal
