Which API is used to define a transformer in the Transformation Service plugin?

• A. transformerDefinition()
• B. transform()
• C. transformerRuelList()
• D. initializeTransformer()

Answer: (A)

In the Transformation Service plugin, setting up a transformer starts with defining its blueprint—the name, input/output fields, and the transformation rules that govern how data is converted. The API used for this defintion is transformerDefinition(), because it is the function specifically responsible for declaring and creating that transformer definition. This is the step that registers the transformer so it can be used later in transformations. Once a transformer is defined, you would use transform() to apply it to data, transformerRuleList() to inspect the rules associated with a transformer, or initializeTransformer() to prepare the transformer runtime. Those options serve roles tied to applying, inspecting, or initializing, not to defining the transformer itself.
