filtered_n_paths算法

您可以使用GES提供的接口执行filtered_n_paths算法。示例代码如下:

public void filteredNPaths(GraphClient graphClient) throws ApiException {
    FilteredNPathsParameters filteredNPathsParameters = new FilteredNPathsParameters();
    filteredNPathsParameters.setSource("Vivian");
    filteredNPathsParameters.setTarget("Lethal Weapon");
    filteredNPathsParameters.setK(2);
    filteredNPathsParameters.setN(1);
 
    AlgorithmReq algorithmReq = new AlgorithmReq();
    algorithmReq.setAlgorithmName(AlgorithmNames.FILTERED_N_PATHS);  // 算法名
    algorithmReq.setParameters(filteredNPathsParameters);  // 算法参数
    algorithmReq.addFilter("out", FilterQueryType.EDGE_FILTER, "label_name","labelName", "=", "transfer", 5);
 
    // 根据输入参数执行指定算法
    AsyncAPIResp asyncAPIResp = graphClient.algorithmQuery(algorithmReq);
 
    // 根据算法执行任务id,查询任务执行状态
    QueryJobReq queryJobReq = new QueryJobReq();
    queryJobReq.setJobId(asyncAPIResp.getJobId());
    GesResponse gesResponse =  graphClient.queryAsyncTask(queryJobReq);
    System.out.println(gesResponse);
}
