YedUtils

The YedUtils class has several utility methods to open a GraphMLDiagram in yEd.

How the class works

In order to open the GraphMLDiagram in yEd, the class:

• Serialize the diagram in a file using the GraphmlFactory.saveDiagram(GraphMLDiagram diagram, File file) method
• Open a yEd process (tarting the yEd.exe executable) in the yEd installdirectory on this file

Usage

You first need to get the unique instancz of this class by calling YedUtils.getInstance().

Then you need to set the install directory of yEd by calling the YedUtils.setYedInstallDir(File file) method.

Then for each diagram, you can use one of the following methods:

• The YedUtils.openInYed(GraphMLDiagram diagram, File file) method will save the diagram in a specified file
• The YedUtils.openInYed(GraphMLDiagram diagram) method will save the diagram in file created in the temp directory

Error handling

The methods of the YedUtils class throw a YedProcessException if:

• The install directory does not exist or is not a directory
• There is no yEd.exe execuutable in this directory
• Starting the process fails

Example

   GraphMLDiagram diagram = ...
      
   YedUtils yedUtils = YedUtils.getInstance();
   yedUtils.setYedInstallDir(<the yEd install directory>);
   yedUtils.openInYed(diagram);
