ListRangeExtractor

Extracts the minimum and maximum values found in a list.

For example, if this feature enters this transformer:

somelist{0}.val = 12

somelist{1}.val =  0.5

somelist{2}.val = 8

Then the value assigned to the resulting minimum attribute would be 0.5 and the value assigned to the maximum attribute would be 12.

Note that non-numeric minima and maxima may also be extracted.  For example, if this feature enters this transformer:

somelist{0}.val = 'apple'

somelist{1}.val = 'donut'

somelist{2}.val = 'aardvark'

Then the value assigned to the resulting minimum attribute would be 'aardvark' and the value assigned to the maximum attribute would be 'donut'.

If some values are numeric and some are not, the minimum and maximum values extracted may not be useful.

Parameters

General

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.
