Transformers in Series

Much like a set of components in an electrical circuit, a series of Workbench transformers can be connected to have a cumulative effect on a set of features.

Chaining Transformers

Even with the large number of transformers available in FME, users frequently need a combination - or chain of transformers - instead of a single one.

A string of transformers that graphically represent an overall workflow is a key concept of FME:

In this example, a DuplicateFilter transformer removes duplicate polygon features. A Dissolver transformer merges each remaining (unique) polygon with its neighbor where there is a common boundary. Finally, each merged area gains an ID number from the Counter transformer.
