Interface Factory<T>

Type Parameters:

T - the type that the factory creates

All Known Implementing Classes:

ConstantFactory, ExceptionFactory, InstantiateFactory

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
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.
