Java yEd

This is a yEd graph file generator written in Java. It allows to create:

• Nodes with labels
• Node types (optional)
• Directed edges between two nodes
• Edge labels (optional)
• Edge types (optional)

Code examples

Example code is available in the following files:

• Examples.java
• YedDocTest.java
• IoTest.java

Example A

// Set file to write
File file = new File("exampleA.yEd.graphml");
System.out.println("Example file: " + file.getAbsolutePath());

// Create document
YedDoc yedDoc = new YedDoc().initialize();

// Create nodes
String a = yedDoc.createNode("Adrian");
String b = yedDoc.createNode("Benjamin");
String c = yedDoc.createNode("Caesar");

// Create edges
yedDoc.createEdge(a, b);
yedDoc.createEdge(b, c);
yedDoc.createEdge(c, a);

// Write file
Io.write(yedDoc.getDocument(), file);

Example B

// Set file to write
File file = new File("exampleB.yEd.graphml");
System.out.println("Example file: " + file.getAbsolutePath());

// Create and configure a document
YedDoc yedDoc = new YedDoc().initialize();
yedDoc.setFontFamily("Roboto");
yedDoc.setFontSize(14);
yedDoc.setFontStyle("bold");

// Create nodes of different types
int hero = 0;
String s = yedDoc.createNode("Superman", hero);
String b = yedDoc.createNode("Batman", hero);
String h = yedDoc.createNode("Harley Quinn", hero);
int robot = 1;
String r = yedDoc.createNode("Robocob", robot);
String t = yedDoc.createNode("T-1000 ", robot);

// Create edges of different types
int knows = 0;
String knowsLabel = "knows";
yedDoc.createEdge(s, b, knowsLabel, knows);
yedDoc.createEdge(t, s, knowsLabel, knows);
int loves = 1;
String lovesLabel = "loves";
yedDoc.createEdge(s, h, lovesLabel, loves);
yedDoc.createEdge(b, h, lovesLabel, loves);
yedDoc.createEdge(h, t, lovesLabel, loves);
Integer unknown = null;
String unknownLabel = null;
yedDoc.createEdge(r, h, unknownLabel, unknown);

// Write file
Io.write(yedDoc.getDocument(), file);

Usage of Maven and GitHub Packages

Add the following lines to your pom.xml:

<dependencies>
	<!-- https://github.com/adibaba/java-yed -->
	<dependency>
		<groupId>de.adrianwilke</groupId>
		<artifactId>java-yed</artifactId>
		<version>(0,1]</version>
	</dependency>
</dependencies>

[...]

<distributionManagement>

		<id>github-adibaba-java-yed</id>
		<name>GitHub adibaba java-yed Apache Maven Packages</name>
		<url>https://maven.pkg.github.com/adibaba/java-yed</url>
	</repository>
</distributionManagement>

To use GitHub Packages, you also have to edit your Maven settings.xml and to create a personal access token. A description on how to set up the settings.xml is available at GitHub Help: Configuring Apache Maven for use with GitHub Packages. Token creation is described at GitHub Help: Creating a personal access token for the command line.

Deployment

• Remove "-SNAPSHOT" from version
• Create a tag, e.g. git tag -a 0.0.0 -m "0.0.0"
• Push the tag: git push --tags
• Create a release from tags/
• Run mvn install and attach binaries to the release
• Create new "-SNAPSHOT" version
