Modying Models

• Transaction operation is required when editing models via API

Example1: Edit class name and its definition

try {
      TransactionManager.beginTransaction();
      BasicModelEditor bme = ModelEditorFactory.getBasicModelEditor();
      // Create a class
      IClass class0 = bme.createClass(project, "class0");
      // Set name
      class0.setName("new class name");
      // Set definition
      class0.setDefinition("Definition of the class");
      TransactionManager.endTransaction();
    } catch (InvalidEditingException e) {
      TransactionManager.abortTransaction();
    }
   

Example2: Edit physical name of ER Entity

IERModel erModel = (IERModel) getElement(project.getOwnedElements(), "ER_Model");
schema = erModel.getSchemata()[0];
IEREntity[] entities = schema.getEntities();
for (int i = 0; i < entities.length; i++) {
   if ("Entity0".equals(entities[i].getName())) {
   try {
     TransactionManager.beginTransaction();
     // Set physical name
     entities[i].setPhysicalName("entity0 physical name");
     TransactionManager.endTransaction();
   } catch (InvalidEditingException e) {
     TransactionManager.abortTransaction();
  }
}
