AttributeManager

Alters multiple attributes through adding, renaming, copying, deleting and re-ordering. Sets values for new, existing, and modified attributes to any combination of constants, attribute values, conditionals, expressions, and parameters. Values can reference adjacent features.

Jump to Configuration

Typical Uses

  • Create a new attribute, and set default or new values for it in a variety of ways
  • Modify existing attributes by renaming, and deleting them, and set or clear values for them
  • Re-order attributes
  • Set an attribute value based on features that come before or after the current feature
  • Simplify a workspace by consolidating multiple attribute-manipulating transformers into one place

How does it work?

Attributes of the input features are presented in a matrix of rows and columns, where you can perform multiple tasks. All features that pass through the AttributeManager are modified according to the selections made in the parameters.

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.
