Class BaseTransformer<T>Abstract

Example

// Creates a one-to-one relationship between two transformers
transformer.item(value)

// Creates a one-to-many relationship between two transformer
transformer.collection(values)

// Wraps the value inside a Maybe to allow undefined values when forming a relation
transformer.whenLoaded(value)

// Lazily compute value when a conditional is true. A simpler way of writing ternary
transformer.when(conditon, () => computeValue())

// Sets the value when an aggregate was computed for the relationship. Think
// of it as a shorthand of self reading the value from the $extras object
transformer.whenCounted('relationName')
