Which statement is not true regarding custom transformers?

• A. Custom transformers appear in the Navigator, Transformer Gallery, and Quick Add menu.
• B. Custom transformers can be created from scratch or by incorporating transformers already added to the Canvas.
• C. Custom transformers can have a name and description.
• D. Custom transformers require writing code to create.

Answer: (D)

Custom transformers are built as reusable blocks through a visual Editor in FME Desktop. You can create them from scratch or by wiring together existing transformers that are already on the Canvas, then save them with a name and description so others can understand their purpose. They show up in the Navigator, Transformer Gallery, and Quick Add menu, making it easy to reuse them across projects. The key point is that creating a custom transformer does not require writing code; the definition is done graphically. You can add code only if you choose to inside specific code-based components, but coding is not a necessity to create the custom transformer itself.
