    }
    if (erGraph.getNodeCount() < 1) {
        return;
    }
    for (TablePart table : tables) {
        List conns = table.getSourceConnections();
        for (int i = 0; i < conns.size(); i++) {
            RelationshipPart relationshipPart = (RelationshipPart) table.getSourceConnections().get(i);
            Edge edge = buildEdgeRelation(relationshipPart);
            erGraph.addEdge(edge);
            partNodesMap.put(relationshipPart, edge);
        }
    }
    ERDirectedGraphLayout erLayoutor = new ERDirectedGraphLayout(erGraph);
    erLayoutor.layout();
    for (TablePart table : tables) {
        setFigureBounds(table, startX, startY);
    }
}

Example 2 with Edge

    if (sourceNode == null || targetNode == null) {
        return null;
    }
    sourceNode.addTargetNode(targetNode);
