Intent

Define a factory of immutable content with separated builder and factory interfaces.

alt text

Applicability

Use the Factory Kit pattern when

  • a class can't anticipate the class of objects it must create
  • you just want a new instance of a custom builder instead of the global one
  • you explicitly want to define types of objects, that factory can build
  • you want a separated builder and creator interface
