yFiles Tutorial Ports Demo

The following files make up the tutorial ports demo. The demo shows how

nodes that have a fixed set of ports can be implemented
view modes can be written that allow edge connections to fixed ports only
how nodes with fixed ports can be serialized in GML and YGF format.

Directory resource contains sample graph files and images.

Class	Description
demo.view.ports.PortsDemo	The main demo program in this tutorial.
demo.view.ports.FixedPortsNodeRealizer	A NodeRealizer implementation for nodes that have a fixed set of ports. Used in the PortsDemo.
demo.view.ports.EncoderFactory	Provides an extended GML encoder that can handle fixed port lists for nodes. Used in the PortsDemo.
demo.view.ports.ParserFactory	Provides an extended GML parser that can handle fixed port lists for nodes. Used in the PortsDemo.

Running the Demos

From Within an IDE

Set <yFilesDir>/src as your source directory. Then add <yFilesDir>/lib/y.jar and the source folder <yFilesDir>/src to your classpath. Now you should be ready to compile and run all executable demo classes.

With Ant

First make sure you have the build tool Ant installed on your system. Now you can use the demo build script build.xml located in <yFilesDir>/src/demo to launch each demo by specifying its simple class name as a target. Alternatively, launch the interactive demo driver by specifying run as target to conveniently access all demos.
