public interface Factory<T>
Defines a functor interface implemented by classes that create objects.
A Factory
creates an object without using an input parameter.
If an input parameter is required, then Transformer
is more appropriate.
Standard implementations of common factories are provided by
FactoryUtils
. These include factories that return a constant,
a copy of a prototype or a new instance.
