registerFutureVertexForPrefetching

void registerFutureVertexForPrefetching(org.apache.tinkerpop.gremlin.structure.Vertex futureVertex)

Registers a vertex which will pass this step at some point in the future. The vertex is typically known because a traverser at that vertex location has passed a previous step earlier. Using that information, a step can know in advance a set of vertices which it will have to handle in the future.

Parameters:

futureVertex - The vertex which will reach the step in the future.
