Populates a new list from a series of attributes.

The attributes to be used are specified by the prefix parameter. Each attribute's index in the list is specified by everything in the attribute name after the prefix.

The geometry of each feature entering the transformer is not changed.

For example, if the prefix parameter is set to "bob," and a feature entered the transformer with the following attributes:

  bob0 = 'cat'

  bob1 = 'dog'

  bob2 = 'rooster'

  anotherAttr = 'carrot'

then, presuming that the list name specified was "somelist," the feature would now look like:

  bob0 = 'cat'

  bob1 = 'dog'

  bob2 = 'rooster'

  anotherAttr = 'carrot'

  somelist{0} = 'cat'

  somelist{1} = 'dog'

  somelist{2} = 'rooster'

Note that in order for the resulting list to be useful, the source attributes must begin at index 0, and count up without any gaps. For instance, if in the example above, only the bob2 attribute was available, the resulting list would not be valid.

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.
