Interface BeanInfoFactory

All Known Implementing Classes:

ExtendedBeanInfoFactory, SimpleBeanInfoFactory

public interface BeanInfoFactory

Strategy interface for creating BeanInfo instances for Spring beans. Can be used to plug in custom bean property resolution strategies (e.g. for other languages on the JVM) or more efficient BeanInfo retrieval algorithms.

BeanInfoFactories are instantiated by the CachedIntrospectionResults, by using the SpringFactoriesLoader utility class. When a BeanInfo is to be created, the CachedIntrospectionResults will iterate through the discovered factories, calling getBeanInfo(Class) on each one. If null is returned, the next factory will be queried. If none of the factories support the class, a standard BeanInfo will be created as a default.

Note that the SpringFactoriesLoader sorts the BeanInfoFactory instances by @Order, so that ones with a higher precedence come first.
