边过滤查询

GES提供校验边过滤查询接口，您可以使用该接口查询满足过滤条件边的集合。示例代码如下：

  public static void edgeQuery(GraphClient graphClient) throws ApiException
{
//设置边过滤查询
EdgeFilterQueryReq req = new EdgeFilterQueryReq();
//按label过滤边
List<String> lables = new ArrayList<>();
 lables.add("rate");
 req.setLabels(lables);
//设置offset和limit，限制结果个数
 req.setOffset(0);
 req.setLimit(5);
 AsyncAPIResp resp = graphClient.edgeQuery(req);
 String jobId = resp.getJobId();
 EdgeQueryJobReq req1 = new EdgeQueryJobReq();
 req1.setJobId(jobId);
 System.out.println(graphClient.queryJobStatus(req1));
}
