Nullable Any VariableValue Model

The nullable any variable value model describes a single variable that the user may pick from the list of variables. The variable can be of any type.

Example

Check the Editors Example.

Configuration​

import { createNullableAnyVariableValueModel } from 'sequential-workflow-editor-model';

builder
  .property('foo')
  .value(
    createNullableAnyVariableValueModel({
      isRequired: true,
      valueTypes: ['number', 'string']
    })
  );

Optional properties:

  • isRequired - Defines if the value is required. Default value is false.
  • valueTypes - Defines the list of allowed value types. If the list is empty, then all types are allowed.

Value Reading​

The value is stored in a simple object:

interface AnyVariable {
  name: string;
  type: ValueType;
}

To read the value you just need to read the property value:

const value: AnyVariable | null = step.properties['foo']; // { name: 'x', type: 'number' } or null
