Figure 11-4. Category hierarchy before and after code execution

Adding the "Titanic" category to two categories looks the same as adding it to a single category. The

ﬁrst category to which an item (category or other ACSObject) is added is explicitly added as the

default category. If a category/item only has one parent, that parent is implicitly the default.

11.2.2. Deleting a Category

// Fetch the Movies category from the database, assuming its id is 123

Category category = new Category(new BigDecimal(123));

// Delete the Movies category.

category.deleteCategoryAndRemap();
