Interface Factory<T>

Type Parameters:
T - The type of results supplied by this supplier.
All Superinterfaces:
Supplier<T>
All Known Implementing Classes:
ConstantFactory, ExceptionFactory, InstantiateFactory
public interface Factory<T> extends Supplier<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.

Since:
2.1 This will be deprecated in 5.0 in favor of Supplier.
