filter vertices on number of outgoing edges in gremlin titan in java

Question

我想使用java中的gremlin查询和过滤titan中具有超过500个向外边缘的所有顶点...我该怎么做？我已经开始如下

    pipe=pipe.start(graph.getVertices());

Answer 1

You then need a filter function

p.start(
  g.getVertices()
   .filter(new PipeFunction<Vertex,Boolean>() {    
             public Boolean compute(Vertex v) {
               // write your logic here to count edges on the vertex and 
               // return true if over 500 and false otherwise
             }));
