Class ExtendedBeanInfo

java.lang.Object

org.springframework.beans.ExtendedBeanInfo

All Implemented Interfaces:

java.beans.BeanInfo

 class ExtendedBeanInfo
extends java.lang.Object
implements java.beans.BeanInfo

Decorates a standard BeanInfo object (likely created created by Introspector.getBeanInfo(Class)) by including non-void returning setter methods in the collection of property descriptors. Both regular and indexed properties are fully supported.

The wrapped BeanInfo object is not modified in any way.

Since:

3.1
