What Are Transformers?

Transformers are the services you use to accomplish value transformations on the Pipeline tab.

You can only insert a transformer into a MAP step.

You can use any service as a transformer.

This includes any Java, C or flow service that you create and any built-in services in WmPublic, such as the

pub.date.getCurrentDateString and the pub.string.concat services. By using transformers, you can invoke multiple services (and perform multiple value transformations) in a single flow step.
