包路径：edu.uci.ics.jung.graph.Graph
类名称：Graph
方法名：getDest

Graph.getDest介绍

[英]If directed_edge is a directed edge in this graph, returns the destination; otherwise returns null. The destination of a directed edge d is defined to be the vertex incident to d for which d is an incoming edge. directed_edge is guaranteed to be a directed edge if its EdgeType is DIRECTED.
[中]如果directed_edge是此图中的有向边，则返回目标；否则返回null。定向边d的目标定义为与d关联的顶点，其中d是传入边。如果EdgeType是DIRECTED，则directed_edge保证为定向边。
