Managing Diagrams

Reading Diagrams

Here are sample codes that show how to manage Diagram

To iterate on Diagrams

for (Diagram myDiagram : myModel.getInstances(UMLPackage.Literals.DIAGRAM)) {
	...
}

To read the type of a Diagram

SemanticModelBridge bridge = myDiagram.getSemanticModel();
if (bridge instanceof SimpleSemanticModelElement) {
	return ((SimpleSemanticModelElement) bridge).getTypeInfo();
}

To create a Class Diagram

Diagram umlDiagram = model.create(UMLPackage.Literals.DIAGRAM);
umlDiagram.setSemanticTypeInfo(UMLDiagramKind.CLASS_DIAGRAM.getLiteral());

All UML Diagram kinds are available in the Class com.sodius.mdw.metamodel.uml21.xmi.di.UMLDiagramKind.

Managing GraphNodes

Here are sample codes that show how to manage GraphNodes of a Diagram.

To iterate on GraphNodes, contained by the diagram:

for (GraphNode umlGraphNode : umlDiagram.getContainedNodes()) {
	...
}

To find the Diagram Frames of the Diagram:

for (GraphNode umlGraphNode : umlDiagram.getContainedNodes("DiagramFrame")) {
	...
}

To find the GraphNodes, contained by the diagram, represented by the Class "myClass1":

com.sodius.mdw.metamodel.uml21.Class myClass = umlDiagram.eModel().<com.sodius.mdw.metamodel.uml21.Class>getInstances(UMLPackage.Literals.CLASS).detect(UMLPackage.Literals.NAMED_ELEMENT__NAME, "myClass1");
for (GraphNode umlGraphNode : umlDiagram.getContainedNodes(myClass)) {
	...
}

To iterate on all the GraphNodes represented by a Class:

for (Class myClass : umlDiagram.eModel().<com.sodius.mdw.metamodel.uml21.Class>getInstances(UMLPackage.Literals.CLASS)) {
	for (GraphNode umlGraphNode : umlDiagram.getAllContainedNodes(myClass)) {
		...
    }
}

for (GraphNode umlGraphNode : umlDiagram.getAllContainedNodes(UMLPackage.Literals.CLASS)) {
	...
}

To iterate on all the GraphNodes represented by the Class "myClass1":

com.sodius.mdw.metamodel.uml21.Class myClass = umlDiagram.eModel().<com.sodius.mdw.metamodel.uml21.Class>getInstances(UMLPackage.Literals.CLASS).detect(UMLPackage.Literals.NAMED_ELEMENT__NAME, "myClass1");
if(myClass!=null){
	for (GraphNode umlGraphNode : umlDiagram.getAllContainedNodes(myClass)) {
		...
	}
}

To recover the Element represented by a GraphNode:

Element myElement = umlGraphNode.getSemanticElement();

To create a GraphNode in a Class Diagram

GraphNode umlNode = umlDiagram.createContainedNode(class_);
umlNode.setPosition(posX, posY);
umlNode.setSize(width, height);

Managing GraphEdges

Here are sample codes that show how to manage GraphEdges of a Diagram.

To iterate on GraphEdges contained by the diagram:

for (GraphEdge umlGraphEdge : umlDiagram.getContainedEdges()) {
	...
}

To find the GraphEdges, contained by the diagram, represented by the InformationFlow "myInfo1":

com.sodius.mdw.metamodel.uml21.InformationFlow myInfo = umlDiagram.eModel().<com.sodius.mdw.metamodel.uml21.InformationFlow>getInstances(UMLPackage.Literals.INFORMATION_FLOW).detect(UMLPackage.Literals.NAMED_ELEMENT__NAME, "myInfo1");
if(myInfo!=null){
	for (GraphEdge umlGraphEdge : umlDiagram.getContainedEdges(myInfo)) {
		...
	}
}

To iterate on all the GraphEdges represented by an InformationFlow:

for (InformationFlow myInfo : umlDiagram.eModel().<com.sodius.mdw.metamodel.uml21.InformationFlow>getInstances(UMLPackage.Literals.INFORMATION_FLOW)) {
	for (GraphEdge umlGraphEdge : umlDiagram.getAllContainedEdges(myInfo)) {
		...
    }
}

for (GraphEdge umlGraphEdge : umlDiagram.getAllContainedEdges(UMLPackage.Literals.INFORMATION_FLOW)) {
	...
}

To recover the Element represented by a GraphEdge

Element myElement = umlGraphEdge.getSemanticElement();

To create a GraphEdge in a Class Diagram

GraphEdge umlEdge = umlDiagram.createContainedEdge(composition);

Managing GraphConnectors

Here are sample codes that show how to manage GraphConnectors of a Diagram.

To find the GraphNodes connected by a GraphEdge

GraphNode umlFirstNode = umlGraphEdge.getFirstNode();
GraphNode umlLastNode = umlGraphEdge.getLastNode();

To create a GraphConnector in a Class Diagram

GraphConnector firstConnector = model.create(UMLPackage.Literals.GRAPH_CONNECTOR);
sysmlEdge.getAnchor().add(fistConnector);
firstConnector.setGraphElement(sourceNode);
GraphConnector lastConnector = model.create(UMLPackage.Literals.GRAPH_CONNECTOR);
sysmlEdge.getAnchor().add(lastConnector);
lastConnector.setGraphElement(targetNode);
