declare const relationshipValue: any;
const dataTypeProperty: iottwinmaker.CfnComponentType.DataTypeProperty = {
  type: 'type',

  // the properties below are optional
  allowedValues: [{
    booleanValue: false,
    doubleValue: 123,
    expression: 'expression',
    integerValue: 123,
    listValue: [dataValueProperty_],
    longValue: 123,
    mapValue: {
      mapValueKey: dataValueProperty_,
    },
    relationshipValue: relationshipValue,
    stringValue: 'stringValue',
  }],
  nestedType: dataTypeProperty_,
  relationship: {
    relationshipType: 'relationshipType',
