Which parameter helps you tell a transformer to expect a particular arrival order of features?

Which parameter helps you tell a transformer to expect a particular arrival order of features?

• A. FeatureTypeFilter (first feature type arrives first)
• B. Reader order (first reader is read first and so on)
• C. Transformer order (transformers alphabetically by name)
• D. Writer order (first writer is written first)

Answer: (A)

In FME, features flow through a workspace as a stream of different feature types, and some transformers need a predictable order of those feature types to process correctly. The FeatureTypeFilter is the mechanism that lets you specify and enforce which feature type should appear first (and how the stream is routed by type). By configuring it to ensure a particular feature type arrives first, you tell downstream transformers to expect that order, making the processing deterministic and avoiding surprises when multiple types are present. Other options don’t control the in-stream arrival order of features. Reader order affects how sources are read, not the sequence of feature types within the stream. Transformer order describes the execution order of transformers in the workspace, not the feature-type arrival sequence. Writer order concerns how outputs are written, not the internal feature flow.
