如何在Tinkerpop3.4中使用inputstream导入graphml文件

import org.apache.tinkerpop.gremlin.structure.Graph;
import org.apache.tinkerpop.gremlin.structure.io.graphml.GraphMLReader;
import org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerGraph;

import java.io.FileInputStream;
import java.io.InputStream;

public class GraphMLImportExample {
    public static void main(String[] args) throws Exception {
        // 创建TinkerGraph对象
        Graph graph = TinkerGraph.open();

        // 获取GraphML文件的InputStream对象
        InputStream inputStream = new FileInputStream("path/to/graphml/file.graphml");

        // 创建GraphMLReader对象
        GraphMLReader reader = GraphMLReader.build().create();

        // 导入GraphML文件到图数据库
        reader.readGraph(inputStream, graph);

        // 关闭InputStream
        inputStream.close();

        // 其他操作...
    }
}
