regions_selector-1.1.0

Represents a discontinuous transform.

Description

Maps regions to transgorms and evaluates the transforms with the corresponding inputs.

Outline

Schema Definitions

This node must validate against all of the following:

  • This type is an object with the following properties:

    • label_mapper

      ./label_mapper-1.1.0Required

      An instance of label_mapper-1.1.0

    • inputs

      arrayRequired

      Names of inputs.

      No length restriction

      Items in the array are restricted to the following types:

      string

      No length restriction

    • outputs

      arrayRequired

      Names of outputs.

      No length restriction

      Items in the array are restricted to the following types:

      string

      No length restriction

    • selector

      objectRequired

      A mapping of regions to trransforms.

      This type is an object with the following properties:

      • labels

        array

        An array of unique region labels.

        No length restriction

        Items in the array are restricted to the following types:

        [‘integer’, ‘string’]

      • transforms

        array

        A transform for each region. The order should match the order of labels.

        No length restriction

        Items in the array are restricted to the following types:

    • undefined_transform_value

      number

      Value to be returned if there’s no transform defined for the inputs.
