JUNG 既存の 2 つの頂点JUNGを接続して頂点に接続し、余分な頂点を作成するときに、頂点の作成、接続、および色付けのコマンドを取得するためのインターフェイスを実装しています。なぜですか?
connect メソッドのコードは次のとおりです。
public class Connect extends Command {
private CommandMaster cm;
private BehGraphUndirected behGraph;
private static int edgenumber=0;
@Override
public Object run(BehGraphUndirected behGraph, VisualizationImageServer panel, InterpretMaster interpretMaster, String... args) {
System.out.print("connect Runs\n");
this.cm = new CommandMaster();
this.behGraph = behGraph;
if(cm.exists(args[0]))
{
//got to another command
}else
{
switch (args[0]) {
case "edge":
this.createEdge(args[1] , args[2]);
break;
}
}
interpretMaster.refreshAndRepaint();
return null;
}
public void createEdge(String nodeName1 , String nodeName2)
{
this.behGraph.addEdge(edgenumber++,nodeName1, nodeName2);
System.out.println(this.behGraph.getVertexCount());
System.out.println("edge between: "+nodeName1+" and "+ nodeName2+" added");
}
私がコードを実装した方法を知りたい場合に備えて、これは create メソッドです。
package interpreter.command;
import GraphHandling.BehGraphUndirected;
import edu.uci.ics.jung.visualization.VisualizationImageServer;
import interpreter.Command;
import interpreter.CommandMaster;
import interpreter.InterpretMaster;
/**

*/
public class Create extends Command{
private CommandMaster cm;
private BehGraphUndirected behGraph;
@Override
public Object run(BehGraphUndirected behGraph, VisualizationImageServer panel, InterpretMaster interpretMaster, String... args) {
System.out.print("create Runs \n");
this.cm = new CommandMaster();
this.behGraph = behGraph;
if(cm.exists(args[0]))
{
//got to another command
}else
{
switch (args[0]) {
case "node":
this.createNode(args[1]);
break;
case "label":
this.createLabel(args[1]);
break;
}
}
interpretMaster.refreshAndRepaint();
return null;
}
public void createNode(String nodeName)
{
this.behGraph.addVertex(nodeName);
System.out.print("vertex: "+nodeName+" added");
}
private void createLabel(String string) {
}
class str
{
int i;
long j;
}
}

そしてここに私のBehGraphUndirectedクラスがあります：
package GraphHandling;
import edu.uci.ics.jung.graph.UndirectedSparseGraph;
import java.util.LinkedList;
/**
*
* @author Administrator
*/
public class BehGraphUndirected extends UndirectedSparseGraph{
private final LinkedList<Node> nodeList;
public BehGraphUndirected()
{
this.nodeList = new LinkedList<>();
}
public void addNode(Node newNode)
{
this.nodeList.add(newNode);
}
}
