+ * interface.\r
+ * \r

+ * {@link GraphToDiagramSynchronizer} must use this implementation to represent\r
+ * the terminals of the element.\r
+ * </p>\r
+ * \r
+ * <p>\r
+ * Also contains a relative transformation with respect to its parent, a set of\r
+ * allowed drawing directions and a graphical shape to depict the terminal.\r

+ * <p>\r
+ * The specified terminal resource is expected to have at least the following\r
