Factory Object

In object-oriented computer programming, a factory object is an object for creating other objects. It is an abstraction of a constructor, and can be used to implement various allocation schemes, such as the singleton pattern.

Factory objects are used in situations where getting hold of an object of a particular kind is a more complex process than simply creating a new object.

Bean

Lightwire

A very lightweight Direct Injection/IoC engine for directly injecting dependencies into singletons and transient business object.

LightWire is optimized to create transient objects as well as singletons and allows for programmatic as well as XML configuration.

Singleton Pattern

Singleton pattern is a design pattern that is used to restrict instantiation of a class to one object. Involves only one class which is responsible to instantiate itself only one instance and in the same time to provide a global point of access to the instance. In that case the instance can be used from everywhere without calling the directly the constructor each time.
