Note that lazy initialization can also be used in non-object-oriented languages.

Lazy initialization of heap initializes only when required, to improve performance.

Lazy initialization avoids initializing a value until the first time it is accessed.

In a software design pattern view, lazy initialization is often used together with a factory method pattern.

The following is an example of a class with Lazy initialization implemented in Actionscript:

Here is an example of lazy initialization in PHP 5:

Here is an example in Smalltalk, of a typical accessor method to return the value of a variable using lazy initialization.

The drawback is that the enum type is somewhat inflexible; for example, it does not allow lazy initialization.

An attribute's characteristics may include a read/write flag, a type, accessor method names, delegations, a default value and lazy initialization.

The Java (programming language) solutions provided here are all thread-safe but differ in supported language versions and lazy initialization.

It is typically used to reduce locking overhead when implementing "lazy initialization" in a multi-threaded environment, especially as part of the Singleton pattern.

There are four common ways of implementing the lazy load design pattern: lazy initialization; a virtual proxy; a ghost, and a value holder.

In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed.

In software engineering, the Initialization on Demand Holder idiom (design pattern) aka Lazy Initialization Holder Class idiom is a lazy-loaded singleton.
