The BulkAttributeRenamer transforms which of the following?

• A. Attribute Names
• B. Attribute Values
• C. Both attribute names and attribute values
• D. None

Answer: (A)

The BulkAttributeRenamer changes the names of attributes, not their contents. It uses a mapping of existing attribute names to new ones and renames those attributes accordingly, while the values stored in the attributes stay exactly the same. For example, if you map an attribute named old_name to new_name, the feature will have an attribute called new_name with the same value that old_name had. It can rename many attributes in one pass, which is why it’s described as bulk. If you need to change the actual data inside attributes, you’d use a transformer designed for value manipulation (such as a value mapper or an expression-based transformer).
