Interface Factory

All Superinterfaces:
Configurable
All Known Implementing Classes:
FactoryBase, RmiProxyFactory, SpringApplicationContextBasedObjectFactory
public interface Factory extends Configurable
An interface class used to provide findable objects.

Factorys are used by the Finder to find objects they act as different object sources. Adding beans directly to a Spring application context is now the preferred method for instantiating objects. Encapsulating objects within a Factory results in objects that cannot be referenced from the application context. Instead of creating new factories, consider writing a BeanDefinitionParser to create Spring BeanDefinitions.
