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:
“In clear weather the laziest may look across the Bay as far as Plymouth at a glance, or over the Atlantic as far as human vision reaches, merely raising his eyelids; or if he is too lazy to look after all, he can hardly help hearing the ceaseless dash and roar of the breakers. The restless ocean may at any moment cast up a whale or a wrecked vessel at your feet. All the reporters in the world, the most rapid stenographers, could not report the news it brings.”
—Henry David Thoreau (1817–1862)
“The medieval university looked backwards; it professed to be a storehouse of old knowledge.... The modern university looks forward, and is a factory of new knowledge.”
—Thomas Henry Huxley (1825–1895)
