Interface ObjectFactory<T>

Type Parameters:

T - the object type

All Known Subinterfaces:

ObjectProvider<T>

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 ObjectFactory<T>

Defines a factory which can return an Object instance (possibly shared or independent) when invoked.

This interface is typically used to encapsulate a generic factory which returns a new instance (prototype) of some target object on each invocation.

This interface is similar to FactoryBean, but implementations of the latter are normally meant to be defined as SPI instances in a BeanFactory, while implementations of this class are normally meant to be fed as an API to other beans (through injection). As such, the getObject() method has different exception handling behavior.
