The BulkAttributeRenamer always operates on all the attributes on a feature.

The BulkAttributeRenamer always operates on all the attributes on a feature.

• A. Sometimes
• B. Never
• C. False
• D. True

Answer: (C)

BulkAttributeRenamer is used to rename attributes based on a user-defined set of old-to-new name mappings. It does not automatically rename every attribute on a feature unless you explicitly include every attribute in its mapping (or use a pattern that covers them all). In normal use, only the attributes you specify are renamed; other attributes pass through unchanged. For example, if a feature has attributes A, B, C and you map A to Alpha and B to Beta, you’ll end up with Alpha, Beta, and C as C. So the statement that it always operates on all attributes is not true.
