类名称：Direction

Direction介绍

[英]Direction is used to denote the direction of an edge or location of a vertex on an edge. For example, gremlin--knows-->rexster is an OUT edge for Gremlin and an IN edge for Rexster. Moreover, given that edge, Gremlin is the OUT vertex and Rexster is the IN vertex.
[中]方向用于表示边的方向或边上顶点的位置。例如，gremlin——知道-->rexster是gremlin的外缘，rexster的内缘。此外，给定该边，Gremlin是外顶点，Rexster是内顶点。
