Calls the specified FME function, optionally putting the resulting value in the Result Attribute. This is a safe way to run FME functions in Workbench, as they are used in mapping files.
See the FME Factories and Functions documentation page for more information about FME functions.
Parameters
FME Function
Specifies the FME function (@FunctionName) to be called, as well as any parameters it can take.
Result Attribute (optional)
The value returned by the FME function called can be specified in this result attribute.
Configuration Line (optional)
Can be specified if the underlying FME function requires it.
Example
The @Reformat function requires a configuration line. To employ it within a workspace, the function would be called like this:
@Reformat(DestDecodeSrcEncode,BinaryKey,Company_Id)
and the configuration line which defines the "BinaryKey" binary structure would be specified as:
Reformat STRUCT_DEF BinaryKey_Part1 BigEndianInt(4,1) _Part2 BigEndianInt(4,5)
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.
