Lazy Initialization - The "lazy Factory"

The "lazy Factory"

In a software design pattern view, lazy initialization is often used together with a factory method pattern. This combines three ideas:

  • using a factory method to get instances of a class (factory method pattern)
  • storing the instances in a map, so you get the same instance the next time you ask for an instance with same parameter (Multiton pattern, similar to the singleton pattern)
  • using lazy initialization to instantiate the object the first time it is requested (lazy initialization pattern).

    “Baltimore lay very near the immense protein factory of Chesapeake Bay, and out of the bay it ate divinely. I well recall the time when prime hard crabs of the channel species, blue in color, at least eight inches in length along the shell, and with snow-white meat almost as firm as soap, were hawked in Hollins Street of Summer mornings at ten cents a dozen.”
    —H.L. (Henry Lewis)
