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. 
Type parameters:
<T> – the type that the factory creates
Since:
2.1/**
