FMEFunctionCaller

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.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
