java - 遍历所有标签

Question

我正在使用 Neo4j 2.0 里程碑 3。

目前有这个工作代码：

String DB_PATH = "/usr/local/Cellar/neo4j/community-1.8.1-unix/libexec/data/graph.db";
GraphDatabaseService graphDb = new GraphDatabaseFactory().newEmbeddedDatabase(DB_PATH);
Transaction tx = graphDb.beginTx();
try {
  Node myNode = graphDb.createNode();
  Label myLabel = DynamicLabel.label('Label_Name');
  myNode.addLabel(myLabel);
  tx.success();
}
finally {
  tx.finish();
}

我将如何使用嵌入式 API 遍历所有具有Label_Name

Answer 1

查看：

GlobalGraphOperations.at(graphDb).getAllNodesWithLabel(DynamicLabel.label('Label_Name'));
