我使用下面的代码
创建了图形并使用Tinkerpop api添加顶点和边缘ArangoDBBatchGraph arang = new ArangoDBBatchGraph("localhost", 8529, "testgraph", "testcollection", "testedgecollection");
Vertex user = null;
Vertex preVertex = null;
preVertex = arang.addVertex(0);
preVertex.setProperty("name", "edgevertex");
long startTime = System.currentTimeMillis();
for(int rec = 1; rec<=10; rec++) {
user = arang.addVertex(rec);
user.setProperty("name", "user"+ rec);
user.setProperty("userid", rec);
user.setProperty("gender", "male");
user.setProperty("firstname", "user");
user.setProperty("lastname", rec);
user.setProperty("employee number", "emp0"+ rec);
arang.addEdge(rec, user, preVertex, "edge"+ rec);
preVertex = user;
}
System.out.println("write Time consumed : "+ (System.currentTimeMillis() - startTime));
但我希望得到图中的所有边和顶点 我尝试了下面的代码,它没有工作抛出异常Exception in thread&#34; main&#34; java.lang.UnsupportedOperationException 在com.arangodb.blueprints.batch.ArangoDBBatchGraph.getVertices(ArangoDBBatchGraph.java:277) 在mydb.ArangodbTest.TestConnection.main(TestConnection.java:54)
startTime = System.currentTimeMillis();
Iterable<Vertex> iter = arang.getVertices();
List<Vertex> list = new ArrayList<Vertex>();
if(iter != null) {
for(final Vertex vert : iter) {
list.add(vert);
}
}
Iterable<Edge> iterEdge = arang.getEdges();
List<Edge> listEdge = new ArrayList<Edge>();
if(iter != null) {
for(Edge edge : iterEdge) {
listEdge.add(edge);
}
}
System.out.println("Read vertices list: "+ list.size() + ", Edges List: "+listEdge+ "; Time consumed : "+ (System.currentTimeMillis() - startTime));
请使用arangodb中的tinkerpop api帮助获取所有边和顶点
提前致谢
答案 0 :(得分:0)
ArangoDBBatchGraph
不支持getVertices()
和getEdges()
方法。您必须使用ArangoDBGraph
代替ArangoDBBatchGraph
。
除此之外,您的代码应该有效。
