AttributeExposer

Exposes attributes in Workbench so they can be used by downstream transformers and writers. This transformer is useful if you know features have an attribute, but that attribute is not currently showing in Workbench. For example:

  • FME Attributes and more obscure Format Attributes that aren't automatically shown in Workbench.
  • Transformers, such as the SchemaMapper, that dynamically add attributes onto features which Workbench is not aware of.

The input features are not modified in any way. This transformer only exposes the attribute in Workbench. It is up to you to ensure the attribute is created or read by the upstream workflow.

Note: Exposing fme_basename or fme_dataset will not change the behavior of the reader. To get these attributes added by the reader, you need to expose them where the read occurs, that is, in the reader feature types or the FeatureReader transformer.

Once the attributes are exposed, they can be used by downstream transformers.

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.
