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.

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.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
