TransactionalEditingDomainImpl editingDomain = (TransactionalEditingDomainImpl) diagramEditor.getEditingDomain();

        editingDomain.getCommandStack().execute(new RecordingCommand(editingDomain) {

            @Override

            protected void doExecute() {

            　　//do something

            }

        });

EMF中模型不能直接编辑，需要有事务，支持undo redo。
