Module Review

This chapter investigated Custom Transformers and how they can be used to improve your FME workspaces

What You Should Have Learned from this Module

The following are key points to be learned from this session:

Theory

• A custom transformer is a sequence of standard FME transformers, condensed into a single unit.
• A custom transformer lets you tidy your workspace, re-use sequences of transformers, and apply advanced functionality.
• Handling parameters in a custom transformer is very important, and can be done either automatically or manually.
• Custom transformer instances point to a definition that is either embedded or linked.
• Custom transformers are used to implement parallel processing.
• Custom transformers are used to implement loops.

FME Skills

• The ability to create, edit and reuse a custom transformer.
• The ability to handle parameters in a custom transformer.
• The ability to export a custom transformer definition.
• The ability to switch types from embedded to linked (or vice versa).
• The ability to use parallel processing.
• The ability to use loops.
