Usage

Creating a diagram

To create a diagram, you must use the GraphMLFactory class. For example:

      GraphmlFactory factory = GraphmlFactory.getInstance();
      GraphmlDiagram diagram = factory.newDiagram();

Note the you can set default values for the diagram elements parameters. See diagram defaults for more information.

Creating a node

To create a node:

      GraphMLNode node = diagram.addNode();

To add a label for the node:

      node.setLabel(<the text>);

To add a description for the node:

      node.setDescription(<the text>);

Creating an edge

To create an edge between nodes:

      GraphMLEdge edge = diagram.addEdge(node1, node2);

To add a label for the edge:

      edge.setLabel(<the text>);

To add a description for the edge:

      edge.setDescription(<the text>);

Creating and using a template

It is possible to create nodes and edges templates to reuse their characteristics.

Diagrams default properties

A diagram have several default parameters which allow to set default values for all nodes and edges created in this diagram.

For example:

      GraphmlFactory factory = GraphmlFactory.getInstance();
      GraphmlDiagram diagram = factory.newDiagram();

      DiagramDefaults defaults = diagram.getDefaults();
      defaults.nodeFillColor = "#FFFFFF";

Opening a diagram

To open a diagram file:

      GraphmlDiagram diagram = factory.openDiagram(file);

Saving the diagram

To save the diagram as a graphml file:

      factory.saveDiagram(diagram, file);
