FME Transformers: 2024.1



Calls a specified FME function, optionally storing the resulting value in an attribute.

Jump to Configuration

Typical Uses

  • In rare cases, calling a specific FME function.

How does it work?

The FMEFunctionCaller may be inserted anywhere in a workspace, and runs individual FME functions. It is a legacy transformer that exists for backward compatibility, and should rarely (if ever) be used.

It may not support newer FME functions. Functions that are not supported will produce an error message indicating that the function is not recognized.

Information about FME functions may be found in the FME Factories and Functions documentation page - as noted above, not all functions will be supported in this transformer.

You may provide an attribute name to store the result in, and specify a configuration line for those functions that require one.
