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).

Famous quotes containing the words lazy and/or factory:

    Take us generally as a people, we are neither lazy nor idle; and considering how little we have to excite or stimulate us, I am almost astonished that there are so many industrious and ambitious ones to be found; although I acknowledge, with extreme sorrow, that there are some who never were and never will be serviceable to society. And have you not a similar class among yourselves?
    Maria Stewart (1803–1879)

    I cannot believe that our factory system is the best mode by which men may get clothing. The condition of the operatives is becoming every day more like that of the English; and it cannot be wondered at, since, as far as I have heard or observed, the principal object is, not that mankind may be well and honestly clad, but, unquestionably, that the corporations may be enriched.
    Henry David Thoreau (1817–1862)
