intersectionItems

intersectionItems(t: Type): Array<Type>

Returns an array of all the types that define a given Intersection type. This function fails if the input is not an Intersection type.

Introduced in DataWeave version 2.3.0.

Parameters

Name	Description
t	The type to check.

Example

This example shows how intersectionItems behaves with different inputs. Note that the AType variable defines an Intersection type {name: String} & {age: Number} by using an & between the two objects.
