Examples of XMLIntrospector

org.apache.commons.betwixt.XMLIntrospector

XMLIntrospector an introspector of beans to create a XMLBeanInfo instance.

By default, XMLBeanInfo caching is switched on. This means that the first time that a request is made for a XMLBeanInfo for a particular class, the XMLBeanInfo is cached. Later requests for the same class will return the cached value.

Note :

This class makes use of the java.bean.Introspector class, which contains a BeanInfoSearchPath. To make sure betwixt can do his work correctly, this searchpath is completely ignored during processing. The original values will be restored after processing finished
