You are here: Infrastructure > EnvironmentVariableFetcher


Fetches the specified environment variable and includes it in a new attribute.

Environment variables are convenient especially if certain standard folders and parameters need to be referenced in a workspace, but the actual locations or names can vary from computer to computer.

The available variables will depend on which platform you are using. For example in Windows you can find a list of variables on your system by opening Control Panel > System > Advanced (or Advanced system settings link in Vista)> Environment Variables.


Usage Notes

Within an FME workspace you could use the value retrieved to:

  • Define the output location of a dataset (in conjunction with Feature Type Fanout, which is described in the Workbench help files)
  • Define the location of a file for the AttributeFileWriter or AttributeFileReader
  • Define the location of a workspace to run with the WorkspaceRunner
  • Write the value to some type of metadata output

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.
