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.
Parameters
Environment Variable
Type the environment variable name (for example, PATH or TEMP).
Attribute
If the specified environment variable does not exist, an empty string is put into the given attribute.
Usage Notes
Within an FME workspace you could use the value retrieved to:
- 定义数据集的输出位置（与工作台帮助文件中描述的功能类型Fanout结合使用）
- Define the location of a file for theAttributeFileWriterorAttributeFileReader
- Define the location of a workspace to run with theWorkspaceRunner
- Write the value to some type of metadata output
Editing Transformer Parameters
使用一组菜单选项,变压器参数s 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, seeTransformer Parameter Menu Options.
