FeatureReader

Reads features from any FME-supported format. A complete read is done for each feature that enters the Initiator port. The features resulting from the read are output either through named output ports or through the generic output port.

The features read can be constrained by specifying a WHERE clause or a spatial filter for formats that support them. Most reader settings and constraints can be configured dynamically from attribute values on the input features.

Additionally, a schema feature representing the feature type definition is output for each encountered feature type. The schema features can be used to configure feature type definitions for dynamic writing.

Output Ports

Output ports can be optionally generated for all or a subset of the feature types available to read. Features that do not have a generated output port will exit the generic output port. In order for output ports to be generated, the reader must be fully specified and accessible.

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.
