Editing Lazy initialization (section)

==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 create instances of a [[Class (computer programming)|class]] ([[factory method pattern]])
* Storing the instances in a [[Associative array|map]], and returning the ''same'' instance to each request for an instance with ''same'' parameters ([[multiton pattern]])
* Using lazy initialization to instantiate the object the first time it is requested (lazy initialization pattern)
